A continuous random variable X is constrained to a peak A continuous random variable X is constrained to a peak magnitude M that is – M < x=””><> (a) Show that the differential entropy of X is maximum when it is uniformly distributed, as shown by (b) Show that the maximum differential entropy of X […]

Show that, with a non-uniform quantizer, the mean-square value Show that, with a non-uniform quantizer, the mean-square value of the quantization error is approximately equal to (1/12) Si ?2i pi, where ?i is the ith step size and pi is the probability that the input signal amplitude lies within the ith interval. Assume that the […]

Show that the power spectral density of a CAP signal with a Show that the power spectral density of a CAP signal with a total of L amplitude levels is defined by S(f) = s2A/T |P(f)|2 where |P(f)| is the magnitude spectrum of the pass band in phase pulse p(t); the s2A is the variance […]

A continuous-wave (CW) beacon transmitter is located on a satell A continuous-wave (CW) beacon transmitter is located on a satellite in geostationary orbit. The beacon’s 12 GHz output is monitored by an earth station positioned 40,000 km from the satellite. The satellite transmitting antenna is a 1m dish with an aperture efficiency of 70 percent, […]

A continuous-time sigA continuous-time signal is sampled and then transmitted as a PCM signal. The random variable at the input of the decision device in the receiver has a variance of 0.01 volts2 (a) Assuming the use of polar NRZ signaling, determine the pulse amplitude that must be transmitted for the average error rate not […]
