ABSTRACT:
A technique covered by patent applicaton S.N. 07/672,309 divides power of an input signal to two A/D converters. A processor receives the outputs of the two A/D converters. The input signal is subjected to a known delay .tau. for one of the converters, and both original and delayed signals are sampled simultaneously. Both sampled signals are Fourier transformed and the phase and amplitudes calculated, using the expressions:
