Determine whether filter System object is FIR
whether the filter System object™
an FIR filter. If the filter is FIR,
To determine whether
sysobj is an FIR filter,
if the filter in the transfer function form has a scalar denominator.
If it does, it is an FIR filter.
Design a Lowpass FIR Filter.
d = fdesign.lowpass; h = design(d,'Systemobject',true)
h = dsp.FIRFilter with properties: Structure: 'Direct form' NumeratorSource: 'Property' Numerator: [1×43 double] InitialConditions: 0 Use get to show all properties
Determine if the filter is an FIR filter using
ans = logical 1
isfir returns 1 to indicate that the filter is an FIR filter.
