In the cascade realization of high order active filters, the sequence of cascading is based on the considerations of maximum dynamic range and signal to noise ratio. To determine the optimum sequence, the classical method requires cumbersome and tedious calculations. Simpler methods were suggested, but were not proved very satisfactory in practive. Here we present a new method for the arrangement, and through an example of the computation of a tenth order elliptical band-pass filter, show its validity...

高阶有源滤波器级联实现时,各级顺序的安排,是从动态范围最大和信噪比最大出发考虑的。决定顺序的安排,过去已有的方法,需要繁复的计算。阶数高时,计算量更为可观。也有人提出过简单的安排方法,但实践证明,并不恰当。本文提出新的安排方法,简单而符合实际,并通过一个十阶带通椭圆型滤波器的计算,作为例子,说明这种方法的依据。

The presently existing method for determination of the optimum sequence requires cumbersome calculations, the labour of which would be heavier for higher order functions.

In the cascade realization of active filters, the selection of the sequence of cascading is based on the principle of largest dynamic range and highest signal to noise ratio, with regard also to some-other effects. The presently existing method for determination of the optimum sequence requires cumbersome calculations, the labour of which would be heavier for higher order functions. Some simple methods had been suggested, but the results were not very successful. This paper is concerned about the elliptic type bandpass filter (which are most popularly used for higher technical requirements)and it presents a new method for determining the optimum sequence of cascading which is simple and versatile. Through practical examples, we have shown the ground for this method.

有源滤波器级联实现时,级联顺序的安排,是从动态范围最大与信噪比最高的原则出发,兼顾其他影响而决定的。过去已有的决定方法,需要繁复的计算,在高阶数时,计算量更为可观。也有人提出过简单的安排方法,但通过实际计算,说明并非最佳。本文就椭圆型带通滤波器(这是对较高要求使用最多的类型,也是用过去已有方法需要计算量最多的)提出新的安排顺序的方法,简单而符合实际,并通过实例,说明这种方法的依据。
