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.
Given the block diagram of a synchronous counter shown in Figure (a), draw the timing diagram for the first input pulses, with Q 1 , Q 2 , and Q 3 initially at 0.
HOW TO DESIGN
construction and its working
Q. The response y(t) of a linear system to an excitation x(t) = e -2t u(t) is y(t) = (t + 2)e -t u(t). Find the transfer function.
Draw and explain the circuit of feedback amplifier
Q. What are transmission bridges? How do they assist in satisfying the connectivity? Ans: A typical transmission bridge is demonstrated in figure. Series capacitance and shunt
Q. Determine the transfer function C(s)/R(s) of the nested-loop feedback system shown in Figure.
Q. Some element voltages and currents are given in the network con?guration of Figure. Determine the remaining voltages and currents. Also calculate the power delivered to each ele
The first three elements of the task are: 1. To critically examine a selection of the components used on this design 2. To recommend materials to be used in making the board
Q. A JK flip-flop is shown in Figure (a). (a) Modify it to operate like the D flip-flop of Figure (b). (b) Modify the JK flip-flop to operate like the T flip-flop of Figure (
