Parameters

FIRIntegration

For each sample of input, the FIRFilter computes the convolution of past samples with FIR filter coefficients. When FIRIntegration is set to "none", this is also the filter's output. When FIRIntegration is set to "mean", "rms", or "max", the respective computation is performed, and the result returned in the output signal's first sample (element, bin).

FIRCoefficients

A matrix of FIR filter coefficients. Here, rows correspond to channels, defining an individual FIR filter for each channel. When an empty matrix is specified, the FIRFilter returns its input signal unchanged.

States

None.
