A message signal of frequency 10kHz and ...

A message signal of frequency `10kHz` and peak voltage of `10"volts"` is used to modulate a carrier of frequency `1 MHz` and peak voltage of `20"volts"`. Determine
(`a`) modulation index
(`b`) the side bands produced.

Text Solution

Verified by Experts

(`a`) modulation index `=10//20=0.5`
(`b`) The side bands are at
`(1000+10)kHz=1010`
`kHz` & `(1000-10kHz)=990kHz`. Are frequency
