Question

15.30 An audio signal is modulated by a
carrier wave of 20MHz such that the
bandwidth required for modulation is 3kHz.
Could this wave be demodulated by a diode
detector which has the values of R and Cas

() R- 1 ko, C 0.01uF
(i) R - 10 kQ, C 0.01uF.
() R- 10 kO, C-0.1uF.​

Answer 1

A 1000kHz carrier wave is modulated by an audio signal of frequency range 100-5000 Hz. Then the width of the channel in kHz is
