Q. Write a note on feedback of emitter follower?
The emitter follower can be seen to be an example of negative feedback when the relationship
is put in the form
Which when compared to
shows that B=1. The gain with feedback is
The gain of 1 can be seen as a result of all the output being fed back to the input.
Explain the Limiting the Spectrum This low-pass filter is known an anti-aliasing filter. These filters are originated at the input to most applications. Since they are required
Q. The energy stored in a 2-µH inductor is given by w L (t) = 9e -2t µJ for t ≥ 0. Find the inductor current and voltage at t = 1 s.
