| 内容記述 | In the previous paper, the authors have shown that the output pulse rate of the EMF-detector excited by a pulse train of commercial frequency is a measure of the imput emf applied between the bases of the transistors, and that the ratio of proportionality is determined by the variance of the noise. They have also shown that the residual potentials of the interconnecting capacitances can give a dead zone to the pulse rate vs. emf curves and they have given theoretically derived expressions for the pulse rate vs. emf, the residual potential as a parameter. In the present paper written as the sequel of the previous, are described the experimental results of the detector excited by a pulse train whose frequency is other than the commercial frequency. It is found that the characteristics of the output pulse rate are very different from those excied by the commercial frequency, giving rather a wide proportional part. These results are theoretically discussed and are explained as mainly due to the intervening sinusoidal noise of commercial frequency. In the latter part of the present paper are treated analytically the phenomena occurring at the starting instant of each exciting pulse. It is concluded that the time required before the establishment of on- and off- states increases with the ratio (Ep -Eb) /e, where e is the input emf and that even for the ratio of (Ep -Eb) /e as large as 10^4, the time required is very short, that is, of order of 10^-12 sec only. | |||||
