Question: The threshold level for an envelope detector is sometimes defined as that value of (SNR) T for which A c > r n with probability

The threshold level for an envelope detector is sometimes defined as that value of (SNR)_Tfor which A_c > r_nwith probability 0.99. Assuming that a²m̅²_n≅ 1, derive the SNR at threshold, expressed in decibels.
