Abstract
A signal processor suitable for real time processing of a complex signal having a relatively narrow frequency spectrum is disclosed. Such signal processor includes a so-called delay line time compressor adapted to receive digital signals corresponding to samples of the complex signal into selected stages thereof and to convert such digital signals into a resulting complex signal, analogous to the complex signal being processed, but having a relatively wide frequency spectrum. The signal processor also includes a digitally controlled oscillator in combination with a single side band generator to produce frequency-varying heterodyning signals which, when mixed with the resulting complex signal, permit separation of the frequency components of such resulting signal to permit any further separate processing of each one of such components.
