NOTES:
1. The circuit components are designed to provide an effective "brickwall" bandwidth from 10 Hz to 10 kHz.
2. Measurement should be made with a true rms voltmeter with at least 20 kHz bandwidth.
3. The filter pole frequencies are related to the effective noise pass band frequencies as follows:
fLE = 2/n x fLP; fHE = n/2 x fHP.
