Abstract :
The real-valued transform is related to the polyphase decomposition of a sequence. This observation is applied for deriving sampling rate conversion systems that are implemented by the real-valued fast cyclic convolution algorithms. The systems include interpolation by an integer factor, decimation by an integer factor, and sampling rate conversion by a rational factor. The proposed implementations are useful when the signals and impulse responses of filters are restricted to be real
