Lowpass FIR Filter Design These problems are due to round-off errors and can occur for n as low as 4. When you do not provide a design method as an input argument, design uses the default design method. 0 ⋮ Vote. Note, however, that minimum-order designs can also be obtained using a Kaiser window. Digital filters are used in a variety of signal processing tasks including outlier and noise removal, waveform shaping, signal smoothing, and signal recovery.
