Datasheet

 

The Krohn-Hite 3364 is a four channel filter providing a tunable frequency range from 0.1 Hz to 200 kHz. The frequence response characteristic is selectable to either maximally flat (Butterworth) for clean filtering in the frequency domain, or linear phase (Bessel) to provide superior filtering of pulse or complex signals.
 

Each channel is a selectable low-pass or high-pass, 4-pole filter providing an input gain of up to 50 dB and an output gain up to 20 dB, selectable in 0.1 dB steps.
