aFilter(a,specs)

Generic classical analog filter

Function only- no corresponding object

Syntax

o_aFilter(a,specs)

a: waveform - input signal to be filtered

b: scalar record - specifications for the filter, with fields

type: scalar int - 0 = butterworth, 1= chebychev

Function: scalar int - 0= low pass, 1= band pass, 2= band stop, 3= high pass

Fl: real scalar - lower cutoff frequency

Fu: real scalar - Upper cutoff frequency

Pr: real scalar - passband ripple in dB

Sr: real scalar - stopband ripple in dB

order: scalar int - classical filter order

return: waveform - filtered signal

Usage

Use this to filter a given signal using classical polynomial-based filter functions.
