A professor pauses a lecture on two-port networks to read students’ cheeky feedback about his teaching, bald head, and moustache before returning to circuits.
0:00 One of the two subtopics of the last chapter, which is transfer functions or network functions, and we are going to start the last subtopic, which is two-port networks. 0:09 So before I do that, let me do a quick review of the topics that we covered last time, which is primarily... 0:29 Please return. Please return your forms. Uh, you can, you can bring them towards the front, in the middle, somehow. 0:42 Over this side, are there any forms? 0:46 Any forms on this side? 0:49 Anyone else who wants to give the forms? 0:59 Anyone else who has to return the forms? 1:07 Okay, if not, thank you. Uh, there's one there, sorry. 1:14 There's one. There's a couple at the back. 1:24 Any more, please, please let us know quickly. 1:36 Okay, thank you, Serene and Meiling. 1:42 Okay, thank you, ladies and gentlemen, for participating in this survey. 1:46 Now, I told you that I'm going to ent- entertain you, right? 1:49 I'm a man of my words, so I'm going to entertain you with some funny comments that your seniors have been writing over the years, and these have become archives, and I'll take them with me to my grave. 2:03 Now, allow me to read. 2:15 For the benefit of those sitting at the back, maybe I can read. 2:19 Says sexy, handsome, erotic. 2:23 Can you show me your chest hair in order to compensate for your bald head, he says, or she says. 2:31 You're supposed to write about my teaching. 2:37 Another one says, I can't take my eyes off of your sexy body, babe. 2:46 Didn't know I was sexy. 2:49 This guy says, you are too attractive. Girls concentrate on you rather than on what you teach. 2:58 And somebody loves me. 3:03 I wish I knew if it was a boy or a girl. I don't want this to be a guy. 3:12 You make me horny, baby. 3:15 Oh my God. What are we having here? Are we having a sex lesson or what? 3:22 They're talking about circuits. How can I make you horny? 3:28 Ji, very interesting. Says shave away moustache so students can concentrate better. 3:35 So now the focus is on my moustache, yeah. 3:40 This guy says he combs his moustache but not his hair. 3:47 Where does that... 3:49 where does that come from? 3:53 Maybe he saw me doing it in the loo or something like that, I don't know. 3:57 Now, this is one of my all-time favorites. Somebody wrote a poem, uh, and it's very nice. 4:02 No grass on the busy road, no hair on the clever head, he says. 4:12 Another person wrote a poem, which is not as nice as that one, but still it's a good effort. 4:16 Says, uh, roses are red, violets are blue, the lesser your hair, the sexier you get. 4:26 That's not trying very well, but still it's a good effort, as I said. 4:31 I cannot talk with my girlfriend even if I left her shit. 4:40 How many of you are in that position? Quite a few. 4:46 No, no, no, let's listen to this, very detailed, very, it's just similar to me. 4:50 Rat- rattles on and on like a shotgun. Slow down. Actually, don't be disappointed that you're a bit bald, but you still can wear a wig, provided it doesn't fall off. 5:01 Anyway, still handsome with or without hair, but anyway, I'm not interested. 5:09 I'm not asking you if you're interested, am I? 5:15 Gee. This one is very nice. Ease your leg off the accelerator. 5:20 This one is nice. Do you use conditioner for your mustache? 5:25 Is it at its maximum length, cos theta equal to 1? 5:30 Oh dear. Fantastic. 5:34 What a way to relate power factor to, wow. 5:38 This is innovation, this is innovation at its best. Is your moustache the source of your knowledge? 5:45 If it is, then please don't set so difficult questions because most of us don't have moustache. 5:54 Amazing. Amazing. 5:56 Well, well, well. So interesting. I don't know what to write. 6:02 Is there anything to improve? Oh yeah, how about making the exams optional? 6:05 Ha ha ha. 6:10 Uh, we can go on and on. We are losing precious time, but that's okay. 6:14 Please slow down, dude. You're not driving a Ferrari in LT23. 6:20 And this one, obviously a jealous boyfriend saying, gals still love balding guys. 6:28 Now this person, obviously after listening to my comments, he says, since everybody calls you babe, I'll call you sweetheart. 6:33 Well, good teaching, sweetheart. 6:38 Well, more and more. Let's, let's just call it off with just a couple more. 6:41 Attending your lectures is like, uh, watching Indian Die Hard, Indian Bruce Willis. 6:48 The world is peaceful when you stop talking, he says. 6:59 More and more on the head and the mustache and whatever else. 7:04 Did you polish your head so shine? 7:08 Well, what more? 7:12 I think we better stop. Maybe the last one here, talk like an M16 set to automatic. 7:17 Please switch to semi-automatic, he says. Okay, we're gonna cut it short because we have to cover a lot of ground. 7:25 So this is what you write for my teaching. 7:29 Very interesting. 7:33 I wish we had more time. There's many, many, many that are sitting in my office like that, and I don't feel like throwing them, uh, because they're so interesting, yeah. 7:42 Okay, where were we? 7:45 You have to come back now. Come back. You, you have to change your mood suddenly. 7:52 Okay, we were talking about two-port network, in case you forgot. 8:00 And we were talking about the six ways in which the two-port network can be described. 8:06 Currents on the left-hand side, you will get admittance parameters. 8:10 Voltages on the left-hand side, you will get impedance parameters. 8:14 Input quantities on the left-hand side, you will get transmission parameters. 8:18 Output quantities on the left-hand side, you will get inverse transmission parameters.
