A power amplifier employs an output stage whose gain varies from 2 to 12 for various reasons. What is the gain of an ideal (non varying) amplifier connected to drive It so that an overall gain with feedback of 100 ± 5% V/V can be achieved? What is the value of beta to be used? What are the requirements if Af must be held wlthm ±0.5 %? For each of these situations, what preamplifier gain and feedback factor beta are required if Af is to be 10 V/V (with the two possible tolerances)?
Write an ABEL program for a combinational logic function with five input bits N4-N0 representing an integer between 0 and 31 and two outputs M3 and M5 to indicate if the number is a multiple of 3 or 5, respectively.
consider the back to back cascade of an ideal C to D and D to C converter. Both have the same sampling rate fs. Suppose that the signal being sampled is: x(t) = cos(324*pi*t - pi/4) + cos(80*pi*t - pi/4)
