Abstract
  • This thesis discusses the analysis, design, and experimental evaluation of an instrument that can be used to detect the presence or absence of a signal, not necessarily known, in a noisy background. The detection principle is based on application of the sign test of distribution-free statistics to the stochastic process defined by the zero-crossing intervals of a signal or signal plus noise process. It is shown that the detector is distribution free in the sense that the false-alarm probability can be evaluated with only a limited knowledge of the statistics of the underlying noise process. A theoretical discussion of the detection principle and false alarm probability analysis is presented in conjunction with design considerations of the circuitry used to implement the zero-crossing analyzer technique. Results of an experimental evaluation with narrow-band noise are presented along with a complete schematic diagram of the analyzer. For a noise filter center frequency of 10.3 kHz and with the signal frequency removed from the filter center frequency by at least 300 Hz, reliable detection can generally be obtained with a signal to noise power ratio of -8 dB.
