Find the sinusoidal steady-state response of vC(t) in Figure P7-33 when R = 100 kΩ, C = 0.02 μF, and the input voltage is vS(t) = 15 cos 50 (t) u (t) V. Repeat for an input voltage of vS(t) = 15 cos 500 (t) u (t) V, and one more time for an input voltage of vS(t) = 15 cos 5k (t) u (t) V.
Describe how changing the frequency affects the output's amplitude and phase. Choose to use MATLAB and plot the steady-state responses of each input on a single set of axes.
A CS amplifier using an NMOS with gm = 3.8 mA/V is found to have an overall voltage gain of -16 V/V. What value should a resistance RS inserted in the source lead have to reduce the overall voltage gain to -8 V/V
A windmill has a diameter of 3 meters. It converts wind enegry to electrical enegy with a efficiency of 40% of the theoretical maxium for windmills. What is the eelctric power output at a wind velcity of 15 miles per hour.
Consider a PCM-TDM system in which 24 signals are to be processed. Each signal has a baseband bandwidth of 3 KHz. The sampling rate has to be 33.3% higher than the theoretical minimum, and 8 bits are to be used.
