Pulse Circuit Class:

After a week of negotiations, Sree finally agreed to give me space for one more post in his
(otherwise blank )blog. About the comments,

Remya : Shikha is too morose to write about. Keeping aside the smiles that we share in proximity, We don’t have any warm feelings for each other. (After all I am not Sreenath to write stories on lost love).

Rajiv : I accept, Sogy is unprecedented in her serious comedies.

Venkat/Deepthi : Thanks for your comments. I presume you both are his colleagues. I admit that he has unique writing style, but only while giving exams. His answers don’t have much relevance to the questions asked.

Now let me tell you a memorable Pulse Circuit lecture hour..

Pulse Circuits:

Semester 4(and we call it as S4). First day of Pulse circuits class. Sallu was behaving differently to me, not because I dint tell her about the new salwar I bought last week, but she came to know that from Reshmi. I had already planned to spent the whole day in class in justifying this. But my last ray of hope rested on Rajiv, who is a maestro in solving the disputes between girls. My justification was interrupted by the entry of Our Pulse Circuit sir. An exception to all government staffs; he entered the class room on time. The decorum of the class just before him entering was no better than a fish market in kerala or t-nagar in Chennai or chudi bazaar near Charminar.

He was young, around 5’7’’, round faced, fair, thick mustache (which was one of my greatest weaknesses then) . Dressed up in half sleeve white check shirt and plain black trousers, the label on which read ‘indigo nation, he was handsome. He reminded me of the mannequin in front of Maharaja’s textile near town bus stand.-

His eyes were lit up with enthusiasm sufficient for us to make out that he is a fresher in the field of teaching. He started the class with mutual introduction. He said ‘I am Krishna’ from ABC engineering college in Tamil Nadu (All engineering colleges are abbreviated to 3 alphabets and in TN there are plenty of them. So let me chose the first 3, which does not have any thing to do with my story).

Each one of us stood in our place to give our name, school and entrance rank(I hated him for this. Why the hell are people obsessed still with the result of an exam which happened 2 years back..). And then, Krisha sir said, ‘Ok let us begin the pulse circuits class.’ He took a chalk piece , turned towards the black (rather grey)board and drew two parallel line and joined them at the top, and asked us, ‘what is this ??’ The moment he asked the question, with the discipline of a Nazi soldiers my 3 bros, Sunny, Vibhi and Shafiq kept head on the bench uniformly, as the heads did not have the answer and raising it high would invite trouble, Rajiv started writing down some notes, Sallu put her pen down and in the pretext to take it she went below the bench and ..I was quite sure that she wouldn’t come up until somebody answers the question. Reshmi was busy taking down some notes, even when the Krishna sir was standing like a statue, and more importantly she turned her page and started writing in the next page!!! ‘When some body asks a question and if you don’t know the answer, never look at the questioners face’..the theory goes without saying.. I went by that law..I helped Sallu in searching her lost pen. Suddenly, he turned towards Sreenath and said, ‘You’. The moment the question was raised, Shikha closed her eyes and started chanting, may be something that would save her beloved friend from this tough situation. Sogy moved towards Smitha and said ‘Whats the big deal..its a inverted bucket..’ ’shhh…’Smitha replied…’No I think it’s a big PI symbol..’sogy made a come back..

Sreenath slowly stood up..And I was quite confident that, he wont answer. Rajiv stopped writing, Reshmi looked up for the first time from her book, Sallu came back to her seat after her underground research.

‘Well’..he started..as if he knew lot about that diagram.’It looks like a square without the 4th side’. Abominable lull captivated the class. Startled by the answer, sir said ‘what ?? can you repeat ???’ For the first time, I felt sympathetic for him. Overpowering with confidence he said ‘what I was trying to say is that in geometry, you call a closed sided figure…’ ‘this is a signal..’ Krishna sir interrupted. The answer was the first ever blow in his career. I must say it was a mighty one to start with. Sogy was gloomy that her answer too was wrong. Krishna sir had planned to move from the pulse signal to transistors and from transistors to the actual topic ‘Multi-vibrator’. But now he decided to skip the intermediate steps and kick started to the topic. He wrote the topic on the board and then kept the chalk below the topic and unknowingly he underlined the word ‘vibrator’ which made all the boys to spring up on to their toes. To their dismay he drew the circuit diagram with many transistors and said ‘This is mono-stable Multivibrator’. Don’t why he loved the black board more than us. Yeah..love is blind..I forgot.. He always turned to the black board and mumbled something. All of us resorted to our activities. I was resolving the ‘new-salwar’ issue with Sallu. Reshmi taking breaks, only to turn the pages of her encyclopedic notebook. Rajiv hyper excited on his finding that Sandhya has bought a new hair clip And Sreenath looking at Shikha so carefully as if he had to record the number of pimples on her face. We had 15 mins break after this class, which Sree, utilized to ask some doubts to Shikha . His face reflected the song he that he sang in his mind‘pal pal pal pal har pal har pal….kaise katega pal har pal har pal’.

75% of the class were in there own world, 10% were regular absentees and the rest 15% includes Shikha , Sogy, Reshmi, Sabi, Manu, Retheesh and few others. Whenever sir paused ‘Any doubts’, Rajiv had a ready made question ‘can you please explain the last circuit diagram once again..’ Class went smooth without any hiccups for 50 minutes, before he concluded the session ‘So today we learned the concept of multivibrators. And I think I am done with today’s class. ’ The words we longed to hear from time he entered the class’. ‘Any questions ? ’ Pin-drop silence for 20 more seconds.’Ok then let me ask you few questions’ Grave yard silence again conquered the room. Sallu kept the pen ready to drop. 3 empty heads behind me dropped again. Before I could watch few more gestures, ‘Who can explain me the complete working of monostable multi-vibrator’ He was confident that no one would give the answer..so his conscience asked him to reframe the question ‘..hmmm..no let me make it simpler…’ keeping his hand on one part of the transistor, and said, ‘now.. when the voltage increases here on the base of this transistor, how would transistor T2 behave???’ He turned towards Reshmi.She said ’Sir, when the voltage increases the current will…’

He interrupted ’Just tell me, will the second transistor be switched ON or OFF’. She said ‘hmm..’ taking 10 more seconds to think and finally said ‘OFF..no..ON…sorry..OFF.. OFF..hmmm..ON..ON….saturated…cutoff…no..ON’. in the 30 seconds she gave almost all possible states of a transistor which she could think of... The second blow in sir’s career…I felt sorry for him. Disappointed he turned towards Rajiv, who had asked him to explain almost all the circuit diagrams twice. ‘OK come on you…’ Rajiv opened his girlish lips for first time to give a technical answer…and said ‘Ooo..’comtemplating for 10 seconds..Sir blurted..’Excellent..it wil be switched OFF’..All of us were surprised..How could his dumb give the answer ???. Sreenath’s mouth wide open to engulf titanic..Fixing the eye of Rajiv, he again posed the second question ’now tell me what will to the transistor T1, current increases in the base of T2???’ Rajiv again opened his mouth to say ‘O’.Sir went ecstatic ’said yes…its gets switched OFF’. The first award and the first blow for Krishna sir happened to be from his first class. Whole of the class went mesmerized. God heard our inner voice and sir said ‘OK..let us meet tomorrow..’ and the bell rang..he went out of the class.. Sreenath, I and Sallu went near Rajiv to know how could he answer..’How could you..man…’ I asked..He said ’see..the transistor can either be in ON or OFF stage..and both of the states start with O. and I just said O..and sir completed..’ he humbly replied and set an example of smart living..what an idea sirji !!!…
