A sinusoidal signal of the form s transmitted from a fixed platform. The signal is received by an antenna which is on a mobile platform that is in motion relative to the transmitter, with a velocity of relative to the direction of signal propagation between the transmitter and receiver. Therefore, the received signal experiences a Doppler shift and (ignoring noise in the receiver) is of the form
Where c is the speed of light. Find the PSD of the received signal if v is uniformly distributed over Qualitatively, what does the Doppler effect do to the PSD of the sinusoidal signal
what is the resonant frequency of the circuit?
In a BWR or PWR, steam is generated with a temperature of about 290 °C. If river water used to receive waste heat has a temperature of 20 °C, what is the maximum possible (ideal) conversion efficiency of the reactor's thermal en..
Consider a unity feedback control system with plant transfer function G(s) and controller transfer function Gc(s). (a) If the phase margin and crossover frequency are adequate but you need to increase the error constant.
A saw, fan, and lube pump all go on when a start button is pressed. Pressing a stop button immediately stops the saw but allows the fan to continue operating. The fan is to run for an additional 5 seconds after shutdown of the saw.
2 single-phase AC motors connected in parallel are fed from a220 volt source. The motors have the following ratings: Motor #1: 220V, POUT = 50 hp, Efficiency = 82%, PF =0.82 lagging Motor #2: 220V, POUT = 75 hp, Efficiency = 86%, PF =0.85 lagging
