Determine whether filter is SOS form
issos(hd) determines whether
quantized filter hq consists of second-order sections.
Returns 1 if all sections of quantized filter hq have
order less than or equal to two, and 0 otherwise.
issoss(hs) determines whether
the filter System object™ hs consists of second-order
sections, returning 1 if true and 0 if
By default, fdesign and design return SOS filters when possible.
This example designs a lowpass SOS filter that uses fixed-point arithmetic.
The fixed-point filter hd is in second-order
section form, as is the double-precision version.
