SLP

Purpose:

Emulates a single pole analog low pass filter.

Syntax:

SLP(series, fc)

series

-

A series or table.

fc

-

A real, the cutoff frequency in Hertz.

Returns:

A series.

Example:

W1: gsqrwave(100, .01, 4)

W2: slp(W1, 10)

 

Low pass filters the squarewave in W1 with a cutoff frequency of 10 Hz. The sample rate is set to the sample rate of the input data.

Remarks:

The single pole analog low pass filter is implemented in the digital domain using the impulse invariance technique.

 

See SLPFREQ to display the frequency response of the single pole filter.

 

See DADiSP/Filters for additional digital filter design techniques and implementations.
