Some supplementations, unifications, and simplifications of the problem of optimum band-width of a filter approximately matched to high-frequency pulsed signal were made in this paper.For a filter approximately matched to a single rectangular high-frequency pulse, the case for a linear system with rectangular freguency characteristic detuned with respect to the rectangular high-frequency signal was discussed and the formula for calculating the optimum band-width of the system was obtained.For the case of pulse trains with uniform amplitudes, simplification and unification of some results of the other authors were made, it was pointed out that there exists a simple relation between the optimum value of attenuation of the delayed feedback system with unlimited band-width and the optimum teeth-width of a comb filter with single-tuned characteristic of the teeth. The comparison between these two systems was made by the use of the data of the other authors.For the case of rectangular pulse trains with non-uniform amplitudes, the accumulation of the rectangular pulse trains with trapezoidal envelope by the delayed feedback system with finite bandwidth was discussed, and formula of the signal to noise ratio at the output terminals was obtained. For finding the optimum bandwidth of the delayed feedback system, some numerical calculations were made, and curves of the signal to noise ratio with respect to the band-width were plotted. From these curves we found that in this case there exists an optimum band-width of the system, the value of which is wider then the optimum band-width of the system in the case of accumulation of rectangular pulse trains with uniform amplitudes.

本文对高频脉冲讯号近似匹配滤波器的最佳通频带问题,作了一些补充、统一和简化。 对单个矩形高频脉冲的近似匹配滤波器,本文讨论了矩形高频脉冲在失谐的情况下通过矩形频率特性系统时的最佳通频带,得出了计算公式。 对于等幅矩形脉冲串的情形,本文将前人的一些结果在计算方面作了简化和统一。明确指出了有衰减但频带不受限制的延时反馈系统的最佳衰减值和具有单谐振回路特性梳齿的梳形滤波器的最佳梳齿通频带间的对应关系,并用文献上的数据作了比较。 对于非等幅矩形脉冲串的情形,本文讨论了频带有限的延时反馈系统对包迹为梯形的矩形脉冲串进行积累的情形,得出了输出端讯噪比的表示式。为了求得最佳通频带,进行了一些数字计算,作出曲线。从曲线中得到这一系统对包迹为梯形的矩形脉冲串积累时,存在有最佳通频带,它的宽度比对等幅矩形脉冲串积累时的最佳通频带为宽。

A Single-tuned Gunn diode oscillator is described, which is similar to Kurokawa circuit, except that resonant cavity empleys H011 mode high-Q cylindrical cavity. The load variation has small effect on oscillator frequency, thus avoiding the frequency jump generally occuring in reflection-cavity-stabilied oscillators when load or temperature varies. The noise level of this oscillator is even lower than that of other oscillators. With proper choice of parameters for the oscillator circuit, the oscillator output power of 30-10bmW can be obtained with its efficiency of 40-60%, and mechanically tunable bandwidth greater than 600MHz. Different material for main cavity and tunable piston of the oscillator are adopted for temperature-compensation. The temperature cycling is conducted in the range of -40℃ to +70℃. As a consequecy, the frequency temperature coefficient is better than 0.08MHz/℃ and the power stability 0.022dB/℃.

AC filters normally consist of a certain number of single tuned filter for several lower harmonics and a high-pass filter for higher harmonics. In case that the harmonic impedance characteristics of the system has been fixed, the harmonic filtering efficacy of the single tuned filter will depend not only on the capacitance (C), but also on L and R values of the filter. The high-pass filter has a feature similar to the above mentioned filter. Further, a method to design filters is described which...

AC filters normally consist of a certain number of single tuned filter for several lower harmonics and a high-pass filter for higher harmonics. In case that the harmonic impedance characteristics of the system has been fixed, the harmonic filtering efficacy of the single tuned filter will depend not only on the capacitance (C), but also on L and R values of the filter. The high-pass filter has a feature similar to the above mentioned filter. Further, a method to design filters is described which can get optimum harmonics filtening efficacy for the electric power system.
