Patent ID: RE41797

Claim:
A system for channelizing an IF a wideband input signal into separated channelized digital output signals, the system comprising, a complex mixer for quadrature demodulation of the IF wideband input signal into a complex signal, a polyphase clock generator for generating polyphase clock signals each having the same clocking signal that is staggered in phase over a clock cycle, a parallel converter comprising a bank of samplers for respective sampling the complex signal into staggered sampled complex signals and comprising a bank of converters for converting the staggered sampled complex signals into respective sampled digital complex signals, each of the samplers of the bank of sampler sampling the complex signals at a rate of the clock cycle at a respective staggered phase, and a parallel filter bank comprising a polyphase filter bank of filters for respective filtering the sampled digital complex signals into respective filtered complex signals and comprising a processor for transforming the filtered complex signals into the channelized digital output signals, the channelized digital output signals being separated from each other and corresponding to a respective plurality of frequency band signals of the IF wideband input signal.
