A message signal of frequency 10 kHz and peak voltage 10 volt is used to modulate a carrier of frequency 1 MHz and peak voltage 20 volt. Find the modulation index.

Text Solution

Verified by Experts

Here, `v_m`=10 kHz, `A_m`=10 V, `V_C`=1 MHz =1000 kHz
`A_c`=20 V
Hence, modulation index `mu=A_m/A_c=10/20=0.5`
