相関検波による平均周波数および平均電力の測定

抄録

This paper is concerned with the problems of measuring the mean frequency and the mean power of a zero-mean, stationary, narrowband Gaussian random signal in the presence of additive Gaussian noise.
An experimental mean frequency measurement system using correlation detection is constructed for the purpose of obtaining practical characteristics. The average output and the output signal-to-noise ratio of the system obtained by experiment are compared with the theoretical values.
A new method for measuring the mean power is also described and analyzed. The new method utilizes the mean frequency measurement system, and the mean power of a Gaussian random signal is determined using a reference sine wave. The results of the theoretical analysis on this method are supporting by experiment.
