Elliptic filter design

Attenuation is a general term that refers to any reduction in the strength of a signal. You see that the design method has changed from Window to FIR constrained least-squares. Plot the magnitude and phase responses. Each of four types of filters (LP, HP, BP, and BS) can be designed as an . The five parameters of a practical filter are defined in Figure 8. You can control whether the block implements an IIR or FIR lowpass filter using the Filter type parameter.
