Abstract
A high speed analog-to-digital converter, for converting an analog input signal (u(t)) with a maximum frequency (F ) to a digital output signal (x(n)) with an output sampling rate (F ) at least double the maximum frequency (F ), comprises a plurality of analog narrowband filters (F -F ) for filtering the analog input signal (u(t)) to produce a corresponding plurality of narrowband signals (X -X ), which is supplied to a corresponding plurality of analog-to-digital converter units (AD -AD ). The converter also comprises sampling and summing circuitry for sampling the outputs of the analog-to-digital converter units sequentially at the predetermined sampling rate (Fs) and summing the resulting sampled signals to produce the digital output signal (x(n)).
