IIR Filter
Description
The filter block IIR Filter designs an IIR filter based on specifications and
filters data using the filter
Input
The input is MxN.
Output
The output is MxN which is the input data filtered with the designed IIR filter

Name
Name specifies the name of the block.
Type
Type specifies the type of filter that should be used. It can either be set to Low-pass or High-pass.
Filtering
Filtering is the way the filter should filter data. It can either be set to Forward which runs data through the filter once
applying half the filter delay, or Forward & Backward filtering data both ways meaning a zero-phase filter.
Design
Design specifies the type of filter design that should be used. It can either be set to Butterworth, Chebyshev I,
Chebyshev II, Elliptic or Bessel/Thomson.
Passband Frequency
The passband edge frequency in Hz is from which frequency the passband requirement maximum ripple should be valid from.
Passband Max Loss
The passband maximum ripple in dB is the maximum ripple allowed in the passband.
Stopband Frequency
The stopband edge frequency in Hz is from which frequency the stopband requirement minimum attenuation should be valid from.
Stopband Min Attenuation
The stopband minimum attenuation in dB is the minimum attenuation the filter should have in the stopband.
Channels
Channels specifies the number of input(s)/output(s) the block will have.
