The diagonal clipping in Amplitude Demodulation (using envelope detector) can be avoided if RC timeconstant of the envelope detector satisfies the following condition, (here W is message bandwidth and ω is carrier frequency both in rad/sec)(a) RC< 1/ W(b) RC> 1/ W(c) RC< 1/ \(\omega\)(d) RC> 1/\(\omega\)

Answer»

(a) RC< 1/ W

It is seen that to avoid negative peak clipping also said diagonal clipping the RC time constant of detector should be

τ< 1/fm

Note fm is maximum modulating frequency i.e. the bandwidth w

RC< 1/w
