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.
