    I dont understand this AC Analysis question.

    Find the TOTAL Z in a-b which is only a single inductor ? What am I suppose to get Total Z excluding 0.5K ohm resistor ?

    I dont understand this AC Analysis question.

    I have this question that I can not quite figure out what to do. I am quite good at AC analysis I believe. This is the question. Question 2,1 is really vague or is it only me? Am I Suppose to get the imaginary part of that inductor and thats it? Thanks

    Class A amplifier problem

    Hi everyone I have a couple of questions regarding this question. Ok so in order to sketch the wave for all the points "A to J" I first need to know if it clips or saturates. I was not given the Gain of either DC or AC so I figured that I am going to have to calculate that first. This is how...

    Bootstrap this amplifier ?

    I see exactly my circuit accept with a Re and the output on the collector. But why would they tell me to convert one from the other? It just seems more and more like they want me to just draw an entirely different circuit ? Thanks

    Bootstrap this amplifier ?

    What about the output? Does it also go to the Collector leg instead of the emitter as it was? Thanks

    Bootstrap this amplifier ?

    Ok soo some research that I have done before posting resulted in this circuit popping up allot. This is the original Emitter Follower with bootstrapping applied. And because of my circuit I thought something like The formula for resistor 3 is. R3, = R3b = R3/ ( 1 - Ao ) But I dont have...

    Bootstrap this amplifier ?

    It is to make a high impedance input by giving some positive feedback.

    Bootstrap this amplifier ?

    I have been through the book a couple of times. Its "electronic devices 9th edition " But I can not find anything resembling that circuit. @FvM Yes I have seen a couple of Bootstrap circuits but I dont know how I am suppose to convert one to another? I know that a cap would be feed back the...

    Bootstrap this amplifier ?

    HI everyone. I received this question to do. My first question is, Is this an normal Emitter follower circuit when the output is take from the Collector? Also what do they mean if they say I have to bootstrap this Amplifier without giving me any values for the components? I dont understand...

    I keep runing in circles around this optic fiber question... Please help

    Hi everyone I can not seem to get the right formulas to finish this question. I keep on beating my head against a wall for hours now. This is what I have. If I could just get the wavelength( λ ) I could easily get the diameter etc. But λ = v/f neither if which I have. WHERE v = Normalized...

    LR Natural Response circuit

    Rtot = ( 1/8k + 1/2K)^-1 = 1.6k ; L = 10x10^-3H ; Tao = 10x10^-3/1600 = 6.25x10^-6 seconds ; V|| = 24V ; i(t) = Ioe^(-t/Tao) ; Io = 24/1600 = 0.015 ; i(t) = 0.015e^(-t/6.25x10^-6) i(t) = 0.015e^(-160000t) Soo at i(10) = 0.015e^(-160000(10)) = 0 .... is this right?

    LR Natural Response circuit

    Hi Everyone. I have what seems to be an easy LR circuit problem I would like to have some input. Is it safe to assume that because first 2K-Ohm resistor is actually in parallel with the 8K-Ohm resistor since the inductor at 0 is a short? Also will the 2K+4.7K = 6.7K also be in parallel with...

    Tricky nodal analysis

    So I drew another diagram and I palced the nodes. Do they look ok? I am not quite sure on how to go about doing this specific SuperNode though. Ok soo this is what I came up with -> **broken link removed** I just dont get how I will go about SUPERNoding this circuit at all? Thanks

    Tricky nodal analysis

    How does this look... I find it awkward to simply convert it without taking other sources etc into consideration?

    Tricky nodal analysis

    Could you maybe show me what you mean?
