en(S) = 0.1 Eo
en(H) = 0.1 E0
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/š x fLP; fHE = š/2 x fHP.
