| 内容記述 | Many researchers have already discussed the advantages of PTM system from he point of view of distortion and crosstalk. The purpose of this paper is tot discuss another significant aspect of any communication system, which is the system signal to noise improvement. The basic mechanisms of fluctuation noise generator of PTM signal is the synchronizing action of pulse oscillator by valve noise. If the pulse time is shorter compare with the build up time of oscillation, the shape of pulse is distorted and the efficiency decreases. In order to improve the SIN, distortion and oscillation efficiency, kernel oscillator is profitable and, moreover, impulsive kernel oscillator has produced many valuable results. These oscillator synchronizes the main pulse oscillation overcoming the fluctuation noise within the range of 60 db. of S/N up to the frequency of microwave signal. | |||||||
