The diagonal clipping in Amplitude Demodulation (using envelope detector) can be avoided if the RC time constant of the envelope detector satisfies the following condition, (ωm is the message bandwidth and ωc is the carrier frequency, both in rad/sec)
1
\(RC<\frac{1}{\omega _m}\)
2
\(RC>\frac{1}{\omega _m}\)
3
\(RC<\frac{1}{\omega_c}\)
4
None of the above
