This paper extends the theory of the general parameter filter without the complex loss zeros with quadrantal symmetry. That is, the loss and the delay time characteristic of pass-bands are Chebyshev-type approximation and the loss characteristic of stopbands can be specified arbitrarily. Because the nonminimum-phase transfer function can be expressed as the product of minimum-phase transfer function and all-pass function, the loss characteristic of nonminimum-phase and corresponding minimum-phase transfer...

This paper extends the theory of the general parameter filter without the complex loss zeros with quadrantal symmetry. That is, the loss and the delay time characteristic of pass-bands are Chebyshev-type approximation and the loss characteristic of stopbands can be specified arbitrarily. Because the nonminimum-phase transfer function can be expressed as the product of minimum-phase transfer function and all-pass function, the loss characteristic of nonminimum-phase and corresponding minimum-phase transfer function is the same and a unique relationship exists between the loss and the phase characteristic of minimum-phase transfer function. A series of new formulas for the loss and the delay time function have been derived, and the Chebyshev-type approximation of the delay time characteristic of pass-band and the initial guess of all available parameters have been obtained. In this respect, this paper presents new ideas and methods. The results of this paper can be used to design varieties of filters including lumped LC filters, active filters, microwave filters, digital filters etc. The results have been made use of in actual applications and have shown great advantages.

This paper presents a general analysis on LC dynamic filter. The inf luences of those factors, such as off-tuning of resonant, decreasing of Q factor and timing shift, on the performance of dynamic filter for channel division are discussed. The computation formulas which provide the theoretical basis for the index distribution in engineering design are derived. Although the analysis is aimed at LC filter, the conclusions and formulas obtained are also suitable for other types of dynamic...

The active Low-Pass filter introdued in this PaPer coordinates RC network into OPerational amplifier to simulate transfer function of LC filter charact eristic. In intelligent instrument, analog quantities are Converted into digit quantities and then some Output digit quantities precessed by micro-brain must be returned to analog quantities. This process brings quantiting noise and interference into existene unavoidably, which must be clearedup. Therefore, one-level filter is cascaded behind output stage. active filter is used in inte lligent instrument because its size is small and amplitude-frequency characteristic is good, but calculations for design is quite tedious. In this paper electronic computer is used for doing a large number of calculations to determine parameters. Data are tabulated, which are suited to practice, so a vast amount of artificial calculations have been reduced and precision has been risen.

本文介绍的有源纸通滤波器,是用RC网络配合运算放大器来模拟LC滤渡特性的传递函数,以构成滤波器——有源滤波器。在智能仪器中,将模拟量转换为数字量,后经微电脑处理及将一些输出的数字量恢复成模拟量的过程。它不可避免地会产生量化噪声和干拢,因此,必须在输出端加一级滤波器,将其消除。有源滤波器体积小,幅频特性好,可用于智能仪器中,但其计算十分繁锁、复杂,本文利用电子计算机进行大量计算来确定其参数,并制成数据表格,它适合于工程上经常采用的查表法。因而减少了大量的人工计算,并提高精度。
