WebbBecause the ideal raised cosine filter has an infinite impulse response, the block truncates the impulse response to the number of symbols that the Filter span in symbols parameter specifies. The Filter span in symbols , N, and the Output samples per symbol , L, determine the length of the filter's impulse response, which is L * Filter span in symbols + 1. WebbThe main parameter of a raised cosine filter is its roll-off factor, which indirectly specifies the bandwidth of the filter. Ideal raised cosine filters have an infinite number of taps. … the emperor\\u0027s new groove tipo
