A symmetric three-level midtread quantizer is to be designed assuming equiprobable occurrence of all quantization levels.

If the input probability density function is divided into three regions as shown in figure, the value of 'a' in the figure is

A signal as shown in figure is applied to a matched filter. Which of the following does represent the output of this matched filter?

Noise with uniform power spectral density of N₀ W/Hz is passed through a filter H(ω ) = 2exp (-jωt_d) followed by an ideal low pass filter of bandwidth B Hz. The output noise power in Watts is

An output of a communication channel is a random variable 'V' with the probability density function as shown in the figure. The mean square value of 'V' is
