Band Pass Filter

Purpose

The Band Pass Filter passes frequency components in the vicinity of the Center Frequency setting. Components above and below the Center Frequency are rolled off at a 6dB/octave rate. Potential applications for the band pass filter include spectrum analyzers and inexpensive crossovers.

Controls

Bandwidth

Adjusts the response characteristic in the immediate vicinity of the Center Frequency. Lower settings produce a sharper response.

Frequency

Selects the center frequency of the filter's response. Components at this frequency pass though the filter un-attenuated.

Graph... (Graphical Frequency Response)

Displays the frequency response of the filter. See the EQ Curve Graphics Display documentation for a complete description.
