Abstract
A wide band analog-to-digital converter used in a frequency multiplexed communication system. The converter includes a plurality, M, of time-interleaved analog-to-digital converter subunits (ADC subunits). The sampling rate, FS, of the M ADC subunits is selected to locate one or more integer multiples of a Nyquist frequency of a respective subunit ADC in one or more guard bands, and/or such that one or more integer multiples of FSare also located in the guard bands.
