ABSTRACT:
A method of digitally processing an analog signal in continuous time includes producing a continuous-time digital signal from an analog signal via a technique that does not include periodic sampling, then producing one or more delayed versions of the continuous-time digital signal. Each delayed version is delayed by nT, where n is an integer greater than zero, and T is a delay interval. The method further includes multiplying the continuous-time digital signal and each of the delayed versions by one or more associated coefficients, so as to produce a set of products, then adding the set of products, so as to produce a sum value corresponding to the analog signal processed by a transfer function defined by the associated coefficients. The individual bit paths of the continuous-time digital signal are multiplied by the coefficients, and the resulting products are combined by a binary-weighted adder.
