Embibe Experts Solutions for Chapter: Communication Systems, Exercise 1: Exercise 1

The communication satellites are parked at a height of (from surface of earth)

Satellite communication is generally carried out for frequencies above

Which of the following is not a transmission channel?

A $\mathrm{TV}$transmission tower has a height of $320 \mathrm{m}$, signal broadcast from this tower will be received by $\mathrm{LOS}$ communication at a maximum distance of $(R_e : 6.4 x {10}^6 \mathrm{m})$

In frequency modulation, the amount of frequency deviation depends on the

A speech signal of $3 \mathrm{kHz}$ is used to modulate a carrier signal of frequency $1 \mathrm{MHz}$, using amplitude modulation. The band width of signal, is

$3‐30 \mathrm{MHz}$ frequency range is known as

Long distance short wave radio broadcasting uses
