WebThis paper presents that the RC polyphase filer has characteristics as a complex analog Hilbert filter. Phase characteristics of the RC polyphase filter have the same as the Hilbert filter. Also its gain characteristics can be approximated as the Hilbert filter; as its order becomes higher, its gain characteristics become closer to the Hilbert ... WebIt is worth noting that if these filters are being used for upsampling/downsampling, the "noble identity" can be used to reduce the CPU cost. The basic idea is that operations that can be expressed in the form: filter that uses z^-N for its states -> downsample by N can be rearranged to use the form downsample by N -> filter that uses z^-1 for ...
