FIR Filter
#
DescriptionThe filter block FIR Filter
designs a FIR filter based on specifications and
filters data using the filter
#
InputThe input is MxN
.
#
OutputThe output is MxN
which is the input data filtered with the designed FIR filter

#
NameName specifies the name of the block.
#
TypeType specifies the type of filter that should be used. It can either be set to Low-pass
or High-pass
.
#
FilteringFiltering 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.
#
DesignDesign specifies the type of filter design that should be used. It can only be set to Kaiser
.
#
Passband FrequencyThe passband edge frequency in Hz
is from which frequency the passband requirement maximum ripple should be valid from.
#
Passband Max LossThe passband maximum ripple in dB
is the maximum ripple allowed in the passband.
#
Stopband FrequencyThe stopband edge frequency in Hz
is from which frequency the stopband requirement minimum attenuation should be valid from.
#
Stopband Min AttenuationThe stopband minimum attenuation in dB
is the minimum attenuation the filter should have in the stopband.
#
ChannelsChannels specifies the number of input(s)/output(s) the block will have.
