在界面的下半部,用来设置滤波器的设计参数,另一部分则是特性区,在界面的design filter部分主要分为:filter type(滤波器类型)...
The Lowpass Filter block independently filters each channel of the input signal over time using the filter design specified by the block parameters. You can control whether the block implements an IIR or FIR lowpass filter using the Filter type parameter. You can specify the passband and stopband...
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...
