WebbIn fact, the raised cosine filter with $\alpha=1$ is the only bandlimited filter that fulfills the 1st and 2nd Nyquist criterion. In the following, let's look at the eye diagrams of several filters and evaluate, which Nyquist Criterions they fulfill. ... First, let's evaluate the eye diagram of the root-raised cosine filter: WebbUse "window method" to design a low-pass FIR filter. The normalized width of the transition band and the required stop band attenuation is what sets the number of taps required. Narrow --> more taps More attenuation --> more taps. The window type determines maximum attentuation and passband ripple.
