Owning Class: filter implementation
Requires: MathScript RT Module
y = filter_zerophase(b, a, x)
Applies a one-dimensional zero-phase filter. filter_zerophase applies the filter, reverses the order of the resulting signal, applies the filter again, and reverses the signal a second time, resulting in zero-phase behavior. filter_zerophase works column-wise for matrices.
|b||Specifies the forward filter coefficients. b is a vector.|
|a||Specifies the backward filter coefficients. If the first backward filter coefficient does not equal 1, LabVIEW normalizes the elements in a by the first backward filter coefficient. a is a vector.|
|x||Specifies the signal to filter. x is a real or complex vector or matrix.|
|y||Returns the filtered signal. y is a real or complex vector or matrix.|
The following table lists the support characteristics of this function.
|Supported in the LabVIEW Run-Time Engine||Yes|
|Supported on RT targets||Yes|
|Suitable for bounded execution times on RT||Not characterized|
