The raised-cosine filter has the property that its impulse response rings at the symbol rate, which means it is capable of minimizing ISI. This property makes the raised-cosine filter the best choice for digital communication systems. The other filters, such as bandpass, low-pass, and Gaussian, do not have this property and may not be as effective at minimizing ISI.
