I am having some difficulty detertming the directions current should flow in an ideal transformer given a certain dot convention. My general understanding in the past was that you simply used conservation of power: V1I1=V2I2, thus if the sign of V2 is opposite of V1, then the sign of I2 must be...
Hi, I am having a bit of a problem regarding a simple proof for a generic energy signal, the question reads as thus:
For an energy signal g(t) with energy Eg, show that the energy of anyone of the signals -g(t), g(-t) and g(t-T) is Eg. Show that the energy of g(at) is Eg/a.
While I can...
Hello, I am having a bit of trouble with the following problem:
Assuming a built in voltage equal to the bandgap voltage, calculate the slowest possible transmit time for a carrier with 5V reverse bias applied to the GaAs photodiode.
I would be able to do this problem without difficulty if...

Hello all,
I haver a circuit design problem that is giving me grief. The problem basically asks to use a circuit with a BJT transistor to drive an LED with a certain maximum current. Thus, the BJT needs to behave as a voltage controlled current source, the prof hinted that the design should...
