Half-band filter is a linear phase FIR filter, which is symmetric-even and odd. Because the coefficient of half-band filter is symmetrical and nearly half of the coefficient are zero, it make the filters reduce the number of multiplication operations by almost 3/4, and the number of ...

To implement the filter, assign the filter coefficients in B to one of the supported System objects. example B = designHalfbandFIR(Name=Value) specifies options using one or more name-value arguments. For example, B = designHalfbandFIR(FilterOrder=30,TransitionWidth=0.2,DesignMethod="kaiser",...
Note: The audioDeviceWriter System object™ is not supported in MATLAB Online. Set up the audio file reader, the analysis filter bank, the audio device writer, and the interpolation filter. The sampling rate of the audio data is 22050 Hz. The halfband filter has an order of 21 and a ...
For ICG, the excitation laser was an 808 nm laser diode at a power density of ~70 mW cm−2, and emission was collected with 1300-nm long-pass filter (Thorlabs). Images and movies were processed with the LightField imaging software 6.11 and MATLAB R2015b. The hindlimb and ...
