4HE FOLLOWING PLOTS DEMONSTRATE THE PERFORMANCE ACHIEVED ON THE
ACTUAL SILICON 40# SHOWS AN &&4 OF A FULLSCALE K(Z SIGNAL
WITH A 4($ . OF n D" WHICH IS DOMINATED BY A SECOND
HAR MONIC 40# SHOWS AN &&4 OF A n D" SINE WAVE DEMON
STRATING THE LACK OF LOWLEVEL ARTIFACTS 40# SHOWS A FREQUENCY
RESPONSE PLOT WITH THE SEVEN EQUALIZATION BIQUADS SET TO AN ALTER
NATING PATTERN OF D" BOOSTS AND CUTS 40# SHOWS A LINEARITY
PLOT WHERE THE MEASUREMENT WAS TAKEN WITH THE SAME EQUALIZATION
CURVE USED TO MAKE 40# 7HEN THE BIQUAD l LTERS ARE NOT IN USE
THE SIGNAL PASSES THROUGH THE l LTERS WITH NO QUANTIZATION EFFECTS
40# THEREFORE DEMONSTRATES THAT USING DOUBLEPRECISION MATH
IN THE BIQUAD l LTERS HAS VIRTUALLY ELIMINATED ANY QUANTIZATION
ARTIFACTS 40# SHOWS A TONEBURST APPLIED TO THE COMPRESSOR
WITH THE ATTACK AND RECOVERY CHARACTERISTICS PLAINLY VISIBLE 4HE
RMS DETECTOR WAS PROGRAMMED FOR NORMAL RMS TIME CONSTANTS
THE HOLDDECAY FEATURE WAS NOT USED FOR THIS PLOT
