WebIn this paper, an optimal design of linear phase digital low pass finite impulse response (FIR) filter using Improved Particle Swarm Optimization (IPSO) has been presented. In the design process, the filter length, pass band and stop band frequencies, feasible pass band and stop band ripple sizes are specified. WebWarning: Odd order symmetric FIR filters must have a gain of zero at the Nyquist frequency. The order is being increased by one. Alternatively, you can pass a trailing 'h' argument, as in firpm(N,F,A,W,'h'), to design a type 4 linear phase filter. Band-pass filter
