Filter Design Categorization
The blocks in the Filter Designs library can be grouped into three categories:
The Digital FIR Filter Design and Digital IIR Filter Design blocks design and implement classical discrete-time windowed filters with standard band configurations (highpass, lowpass, bandpass, or bandstop). The Digital FIR Filter Design blocks additionally offers linear phase multiband and arbitrary shape configurations. The Digital IIR Filter Design block generates Butterworth, Chebyshev type I, Chebyshev type II, and elliptic designs.
See Designing Discrete-Time Classical IIR and FIR Filters below for more about these types of filters.
The Analog Filter Design block designs and implements Butterworth, Chebyshev type I, Chebyshev type II, and elliptic filters in standard band configurations (highpass, lowpass, bandpass, or bandstop).
See Designing Continuous-Time Classical IIR Filters for more about these types of filters.
The Remez FIR Filter Design, Yule-Walker IIR Filter Design, and Least Squares FIR Filter Design blocks design and implement IIR or FIR filters with arbitrary magnitude responses, including multiband responses. The Digital FIR Raised Cosine Filter Design block designs a discrete-time lowpass filter with a raised cosine transition region.
See Designing Discrete-Time Special IIR and FIR Filters for more about these types of filters.
