Abstract
A time diversity carrier signal sampler utilizes a shift register in conjunction with a timer and a plurality of phase samplers. The instantaneous logic level of each phase is measured on a time diversity basis in order to avoid the disadvantageous affects of noise pulses which can occur coincidently on all three phases. The resulting carrier signal data is then provided to a microprocessor for subsequent analysis and phase characteristic determinations. By judiciously selecting the sample and clock frequencies of the shift register, the sampling frequency for each phase and the time between sampling each of the phases can be preselected.
