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.
what is the significant of damping coficient
Q. Forces and torques in magnetic-field systems? We mentioned earlier that the greater ease of storing energy in magnetic fields largely accounts for the common use of electrom
Q. A current of 65 A is measured with an analog ammeter having a probable error of ±0.5% of full scale of 100 A. Find the maximum probable percentage error in the measurement.
Q. Due to what special property does an emitter amplifier work as a buffer amplifier? The circuit design of the emitter follower is such that it has a high input impedance and
A universal shift register can shift in both the left-to-right and right-to-left directions, and it has parallel-load capability. Draw a circuit for such a shift register.
Q. Athree-phase, 60-Hz substation bus supplies two wye-connected loads that are connected in parallel through a three-phase feeder that has a per phase impedance of 0.5 + j2 . Loa
Q. For the circuits shown in Figure, sketch the frequency response (magnitude and phase) of ¯V out / ¯V in .
Capacitor-input filter: The capacitor-input filter, as well called pi filter because of its shape which looks like the Greek letter pi, is a sort of electronic filter. Filter
