WebOutput Signal-to-Noise Ratios in AM and FM on Mac If m(t) = am cos 2πfct, then Pm = am 2 2, K = m / am, and So No = m m 2 2 +2 Si Ni (29.21) For large input SNR and a fixed modulation index, the output SNR is directly proportional to the input SNR. When the input SNR << 1, the envelope signal is WebFM phenomenon. The capture effect is defined as the complete suppression of the weaker signal at the receiver's limiter (if present) where the weaker signal is not amplified, but attenuated.When both signals are nearly equal in strength or are fading independently, the receiver may rapidly switch from one to another and exhibit flutter.. The capture effect …
