freqz2: Frequency response of digital filter

In ravetools: Signal and Image Processing Toolbox for Analyzing Intracranial Electroencephalography Data

Frequency response of digital filter

Description

Compute the z-plane frequency response of an ARMA model.

Usage

freqz2(b, a = 1, fs = 2 * pi, n = 512, whole = FALSE, ...)

Arguments

b	the moving-average coefficients of an ARMA model
a	the auto-regressive coefficients of an ARMA filter; default is 1
fs	sampling frequency in Hz
n	number of points at which to evaluate the frequency response; default is 512
whole	whether to evaluate beyond Nyquist frequency; default is false
...	ignored

Value

A list of frequencies and corresponding responses in complex vector
