An ideal discrete-time lowpass filter with cutoff frequency ωc = 2π/5 was designed using impulse invariance from an ideal continuous-time lowpass filter with cutoff frequency Ωc = 2π(4000) rad/s. What was the value of T Is this value unique? If not, find another value of T consistent with the information given.
A shunt regulator utilizing a zener diode is biased on through a 100-ohm resistor. Determine the change in the regulated output voltage for the two situations below: a) VI changes +2.0 V, ILoad constant b) ILoad changes +100 mA, VI constant
Suppose we want to construct an amplifier with a closed-loop gain of 50. We want the gain to vary by no more than +/- 5% while the open-loop gain varies by +/- 50%. Determine the values for a and b that will satisfy these constraints.

A signal is quantized using PCM. The maximum signal to quantization noise ratio is 20dB. What is the number of uniform quantization levels needed
What are the names of the three regions of the bipolar junction transistor? Why is there a thin region of one material type
y[n]=x[n]+0.8x[n-5000]+0.6x[n-8000] a) Find the delay in seconds for each echo if the sampling rate is Fs=10000 Samp/sec. Td1 and Td2 a) Find the unit sample response for the filter written as the sum of delayed unit-samples.
With the 1s complement scheme, how does the receiver detect errors? Is it possible that a one bit error will go undetected? How about a two bit error?
A buck converter is supplied by a DC source of 48V. It produces an output voltage of 18V across a 10? load resistor. Assume that the capacitor is large enough so that the output voltage is kept constant. Determine the duty cycle D.
