The filter block
FIR Filter designs a FIR filter based on specifications and
filters data using the filter
The input is
The output is
MxN which is the input data filtered with the designed FIR filter
|Passband Frequency||☐ 16000 Hz|
|Passband Max Loss||☐ 1 dB|
|Stopband Frequency||☐ 20000 Hz|
|Stopband Min Attenuation||☐ 60 dB|
Values with ☐ can receive external input.
Name specifies the name of the block.
Type specifies the type of filter that should be used. It can either be set to
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 specifies the type of filter design that should be used. It can only be set to
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.
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 specifies the number of input(s)/output(s) the block will have.
