The Model 3750 is a variable electronic filter that covers the frequency range from 0.02 Hz to 20 kHz, and operates in any one of four functional modes; high-pass, low-pass, band-pass, band-reject. The mode of operation is selected by means of a front panel FUNCTION switch. The pass-band gain is a unity (0db) or 10 (20db), as selected by a front panel GAIN switch, with attenuation slopes of 6, 12, 18, or 24 db per octave, as selected by 2 front panel SLOPE switches.

The cut-off frequencies of both the high-pass and the low-pass sections are independently adjustable from 0.02 Hz to 20 kHz. Operation in the band-pass or band-reject modes permits passage or rejection of any band of frequencies between these limits. In the low-pass and band-reject modes, the filter is direct coupled, passing all frequencies from DC to the selected cut-off frequency of the low-pass section. Ind the high-pass and band-reject modes, the upper 3 db pint is at approximately 1 MHz for 0 db gain, and approximately 200 kHz for 20 db gain.
