Fractional delay digital filters
暂无分享,去创建一个
Fractional delay digital filters (FDDFs) can be used for implementing discrete-time systems which include noninteger delays, i.e., delays that are not multiples of the sampling period. The use of finite impulse response (FIR)-type FDDFs for implementing junctions of digital waveguides is discussed. As examples of useful applications, the fractional delay extension of the Kelly-Lochbaum tube model and a side branch placed at an arbitrary point of a digital waveguide are presented.<<ETX>>
