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

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

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

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

The quantization noise power for the quantization region between –a and +a in the figure is
