37 50,939ABSTRACT OF THE DISCLOSUREA time diversity carrier signal sampler utilizesa shift register in conjunction with a timer and a plural-ity of phase samplers. The instantaneous logic level ofeach phase is measured on a time diversity basis in orderto avoid the disadvantageous affects of noise pulses whichcan occur coincidently on all three phases. The resultingcarrier signal data is then provided to a microprocessorfor subsequent analysis and phase characteristic deter-minations. By judiciously selecting the sample and clockfrequencies of the shift register, the sampling frequencyfor each phase and the time between sampling each of thephases can be preselected.
