Note: The dual envelope "soft"
limiter provides exceptionally good
handling of transients using variable
attack and release time constants. Once activated, the limiter compresses 30+ dB of transmitter
input range into 4.5 dB of receiver output range, thus reducing the measured figure for SNR
without limiting by 4.5 dB
