The Lowpass Filter block independently filters each channel of the input signal over time using the filter design specified by the block parameters.
Design a lowpass FIR filter for data sampled at 48 kHz. The passband-edge frequency is 8 kHz. The passband ripple is 0.01 dB and the stopband attenuation is 80 dB. Constrain the filter order to 120. Get N = 120; Fs = 48e3; Fp = 8e3; Ap = 0.01; Ast = 80; Obtain the maximum...
