EvenSymmetry
EvenSymmetry
is an option of
FrequencySamplingFilter
.
Option
EvenSymmetry
→
True
(the default) results in a linear-phase FIR filter with even symmetry.
h[n] = h[N-n]
where
N
is the filter length.
The option
EvenSymmetry
→
False
results in a linear-phase FIR filter with odd symmetry, such as Hilbert transformers and differentiators
h[n] = - h[N-n]
where
N
is the filter length.
