Passband cutoff set to 0.5. Magnitude specs: rp = 0.2 dB and rx = 40 dB. Design method: Equiripple. Seeking the FIR filter with the minimum stopband cutoff frequency. I want to know the function called for this method so I can include in code dir...
% upper passband edge: w2p = 0.65 pi, Rp = 1 dB % upper stopband edge: w2s = 0.8 pi, As = 60 dB The question is the title itself. Would help me a lot if someone could answer this for me. By the way can someone explain me how the bandpass affected when I change the length...

Understanding the roll-off characteristics of RF filters is fundamental to designing and implementing effective communication systems. Whether prioritizing a flat frequency response, aggressive out-of-band signal rejection, or phase linearity, the choice of roll-off plays a critical role in achieving the...
The Chebyshev filter has a steeper roll-off than the Butterworth filter. But it consists of ripples in the passband (type-1) or stopband (type-2). Type-1 Chebyshev filter is commonly used and sometimes it is known as only “Chebyshev filter”. Type-2 filter is also known as “Inverse ...
used for low amounts of decimation, whereas CIC filters are used along with FIR filters to provide larger down-sampling ratios. IIR filters are a lower order than FIR and provide more efficient implementation when specifications in terms of passband, ripple, stopband and/or roll-off must be ...
The frequency response plot of the filter is shown below, where ωp is the passband ending frequency, ωs is the stopband beginning frequency, As is the amount of attenuation in the stopband. Frequencies b/n ωp and ωs drop in the transition band and are reduced to some lesser degree....

passband to stopband. This means that it is impossible to identify one frequency at which the filter stops passing signals and starts blocking signals. However, engineers need a way to conveniently and concisely summarize the frequency response of a filter, and this is where the concept ofcutoff...
