内容記述 | The focus of this paper is to find out how the output probability density distribution function for a combination of normal random noise and a regular signal with a definite structure is derived after mean squaring rectification,particularly in concrete connection with the signal-to-noise ratio. The above output random fluctuation is treated as a probability problem of“distance" in an N-dimensional functional space with N=2TW (W: frequency interval, T: time interval), where the distance is taken as the mean squared fluctuation. From this point of view, an explicit expression of Bessel type probability density distribution for normal random noise and a regular signal, after passing a mean squaring circuit and ar ectangular band-pass filter of arbitrary width,is theoretically derived by application of the transformation to an N-dimensional polar coordinates. In this case, the output random fluctuation is reasonably expressed by one ripple parameter m. This parameter m is proved to be approximately equivalent to TW expressed in the sampling theorem due to C. E. Shannon. The theoretical resu1ts described in this paper are also applicable to the other fields of measurement on random physical phenomena, since the mean energy (taking a mean squaring form) is a universal physical quantity. | |||||
