PERFORMANCE PLOTS
The following plots demonstrate the performance achieved on the
actual silicon. TPC 1 shows an FFT of a full-scale 1 kHz signal
with a THD+N of –100 dB, which is dominated by a second
harmonic. TPC 2 shows an FFT of a –60 dB sine wave, demon-
strating the lack of low level artifacts. TPC 3 shows a frequency
response plot with the seven equalization biquads set to an alter-
nating pattern of 6 dB boosts and cuts. TPC 4 shows a linearity
plot, where the measurement was taken with the same equaliza-
tion curve used to make TPC 3. When the biquad filters are not
in use, the signal passes through the filters with no quantization
effects. TPC 4 therefore demonstrates that using double-precision
math in the biquad filters has virtually eliminated any quantization
artifacts. TPC 5 shows a tone-burst applied to the compressor,
with the attack and recovery characteristics plainly visible. The
rms detector was programmed for normal rms time constants;
the hold/decay feature was not used for this plot.
