The Krohn-Hite Model 38 Butterworth\/Bessel, plug-in filter card
\nis one of a family of filter cards used in Krohn-Hite Programmable
\nFilter SystemMainframes. It is carefully designed with the user in
\nmind, providing ease of operation, reliability and price
\ncompetitiveness.
\nThe 38 provides a tunable frequency range from 0.03Hz to 1MHz
\nin the low-pass mode and 0.03Hz to 300kHz in the high-pass
\nmode. Both modes are extended down to 0.003Hz with the 002
\noption. The frequency response characteristic is either maximally
\nflat (Butterworth) for clean filtering in the frequency domain, or
\nlinear phase (Bessel) to provide superior pulse or complex
\nfiltering is operator selectable.
\nThe 38 is an 8-pole, wide range, low-pass\/high-pass filter or an
\namplifier providing gains to 70dB in 0.1dB steps. The 38 will
\naccept input signals of \u00b110V peak at 0dB gain and has selectable
\nac or dc coupling. Overload detectors are standard and assist the
\nuser in detecting input signals or incorrect gain settings.<\/p>\n
