Signal to Noise Ratio (dB) at receiver output:
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.
