roll-off is adjustable - see graph above)
Signal to Noise Ratio (dB):
(Note: the dual envelope “soft”
limiter provides exceptionally
good handling of transients
using variable attack and release
time constants. The gradual onset of limiting in the design begins below full modulation,
which reduces the measured figure for SNR without limiting by 4.5 dB)
