By means of a ferrite Faraday-rotator, the performance of an ordinary reflex klystron can be improved. When the output of the klystron is less than a certain specified value, say p, no Faraday-rotation occurs, and thus the r-f signal can be transmitted with very little attenuation. However,when its output is greater than p, a current passed through the solenoid,and Faraday-rotator will attenuate the r-f signals considerably. Such a device tends to limit the amplitude of the microwave energy passing through...

When the output of the klystron is less than a certain specified value, say p, no Faraday-rotation occurs, and thus the r-f signal can be transmitted with very little attenuation. However,when its output is greater than p, a current passed through the solenoid,and Faraday-rotator will attenuate the r-f signals considerably. Such a device tends to limit the amplitude of the microwave energy passing through the device, and therefore called a ferrite microwave limiter. Experimental results of the performance characteristics of an X-band ferrite microwave limiter is presented.

利用法拉第旋轉效应,能够制成一种微波限幅器,用来改善一般反射式速調管的性能。当速調管輸出功率小於某一特定值p时,不产生法拉第旋轉。因此,射頻訊号能够以很小的衰減输出。然而,当它的输出功率大於p时,在磁化线圈中便有电流流过,法拉第旋轉器使得射頻訊号大大地衰減,这样,就使得微波能量通过这一設备时,限制了訊号的振幅。因此称之为铁氧体微波限幅器。实驗結果証明,在三公分波段中用铁氧体微波限幅器来改善反射式速調管的性能是完全可行的。

In many signal processing applications the original signals are usually transformed to some other forms which are more appropriate for processing or are otherwise more desirable. Most of them are linear transforms, such as convolution and matched filtering. A transversal filter has the capability of highly parallel operation, as it can perform a large amount of weighted sum operations simultaneously. Therefore, it is especially suitable to perform various linear transforms. Particularly, the transversal filters, implemented by CCD and SAW devices in sample analog and analog forms, have higher speed of transform, higher packing density and lower power consumption. This paper summarizes the various linear transforms which can be implemented by transversal filters, including chirp-z transform, sliding chirp-z transform, prime transform, discrete cosine transform, discrete cosine prime transform and two dimensional chirp-z transform. This paper also makes some predictions about possible trends in this field in the near future.

在很多信号处理应用中,经常需要将原始信号变换为更便于处理或更期望的形式,这些变换大多为线性变换,例如褶积或匹配滤波等。横向滤波器具有高度并行的运算能力,可以同时完成大量的加权求和运算,因而更适合于完成各种线性变换。特别是由电荷耦合器件和面声器件构成的采样模拟式横向滤波器,更具有较高的变换速度和较低的功耗。本文综述了可采用横向滤波器来实现的各种线性变换,其中包括线性调频z变换、滑动线性调频z变换、素数变换、离散余弦变换、离散余弦素数变换及二维线性调频z变换等,并展望了这方面的发展方向。
