7. ANALOG PERFORMANCE PLOTS
The following CS4340 Analog Performance Plots
were taken from the CDB4340 evaluation board
using the Audio Precision Dual Domain System
Two Cascade. All Base Rate Mode (BRM) plots
were taken at a 48 kHz sample rate with a 20 Hz to
20 kHz bandwidth using a 20 kHz low-pass brick-
wall filter in the DSP Analyzer. All High Rate
Mode (HRM) plots were taken at a 96 kHz sample
rate with a 20 Hz to 40 kHz bandwith using a
40 kHz brickwall filter in the DSP Analyzer.
