FIR Filter
Description#
The filter block FIR Filter designs a FIR 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 FIR 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 only be set to Kaiser.
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.
