For an npn transistor connected as shown in the figure, V_BE = 0.7 volts. Given that reverse saturation current of the junction at room temperature $${300^0}$$ K is $${10^{ - 13}}\,{\rm A}$$, the emitter current is $$\left( {\eta \, = \,1} \right)$$

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