The 3750 Variable Electronic Filter is a multi-function filter that provides band-pass, band-reject, high-pass or low-pass operation, plus independent adjustment of low and high cutoff frequencies over the range of 0.02Hz to 20kHz. The maximum attenuation is 80 dB. In addition, the unit provides variable attenuation slopes of 6, 12, 18, and 24 dB/octave, for each filter section, and selectable pass-band gain of either unit (0dB) or ten (20dB), by means of front panel controls.
