GATE EC 2004 Set 1 Q75 — Analog Communications

A $1 \mathrm{~mW}$ video signal having a bandwidth of $100 \; \mathrm{MHz}$ is transmitted to a receiver through a cable that has $40 \mathrm{~dB}$ loss. If the effective one-sided noise spectral density at the receiver is $10^{-20}$ Watt $/ \mathrm{Hz}$ , then the signal-to-noise ratio at the receiver is

Consider a message signal $m(t)$ which is bandlimited to $[-W, W]$ , where $W$ is in $\mathrm{Hz}$ . Consider the following two modulation schemes for the message signal: Double sideband-suppressed carrier (DSB-SC): $f_{D S B}(t)=A_{c} \: m(t) \cos \left(2 \pi f_{c} t\right)$ Amplitude modulation (AM): …

An amplitude modulator has output (in Volts) $s(t)=A \cos (400 \pi t)+B \cos (360 \pi t)+B \cos (440 \pi t) .$ The carrier power normalized to $1 \Omega$ resistance is $50$ Watts. The ratio of the total sideband power to the total power is $1 / 9$ . The value of $\text{B}$ (in Volts, rounded off to two decimal places) is $\_\_\_\_\_\_\_$ .
