WebYou can use MATLAB ® to design finite impulse response (FIR)-based and infinite impulse response (IIR)-based filters, two common low-pass filter methods.. FIR filters are very attractive because they are inherently stable. They can be designed to have linear phase that introduces a delay in the filtered signal while maintaining the waveform shape.
