Abstract:
1. A signal processing apparatus, comprising: first and second signal inputs for receiving first and second input signals having respective synchronizing characteristics; a first clock generator for generating a reference clock signal, the reference clock signal being independent of the synchronizing characteristics of the first and second input signals; a second clock generator, coupled to the first clock generator, for producing a plurality of further clock signals in response to the reference clock signal; and a signal processing section, coupled to the first and second signal inputs and the second clock generator, for sampling and processing the first and second input signals in accordance with a sampling rate and an appropriate signal standard, the signal processing section having a plurality of analog to digital (A/D) converters that are clocked by respective ones of the plurality of further clock signals, the A/D converters being clocked by respective ones of the plurality of further clock signals, which are independent of the synchronizing characteristics of the first and second input signals and have a frequency substantially equal to the sampling rate, wherein the signal processing section processes the first and second input signals using a single processing channel, the single processing channel being clocked by a further clock signal that has a signal frequency of at least twice the required clocking speed necessary for processing a single one of the first and second input signals.
