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

A carrier is phase modulated (PM) with frequency deviation of 10 kHz by a single tone frequency of 1 kHz. If the single tone frequency is increased to 2 kHz, assuming that phase deviation remains unchanged, the bandwidth of the PM signal is
