Popis:	This paper presents an efficient digital down conversion method for multiple wideband signals. This technique can be used to down convert odd and even subband signals to base band with only one polyphase filter. We can change filter coefficients to receive odd subband signals and then double odd subband bandwidth to receive even band signals. On the other hand, we can keep filter coefficients unchanged and double even subband bandwidth to receive odd band signals.
