摘要
本文依据椭园函数理论，采用切比雪夫逼近法，让相移网络的输出相位差在规定的频率范围内满足切比雪夫条件，以迟近９０°的相位差，设计出一种精确的宽带９０°相移网络。根据设计的数据制作出来的相移网络，测试结果表明相移误差小，性能良好，满足中波单边带立体声广播系统的要求。
An accurate wideband network with quadrature phase-shift is introduced in this paper. Thiswideband network is designed on the basis of the theory of Elliptic function. Chebyshev approxi-mation method is used so that the output singal phase difference of this network conforms toCheby shev conditions and approximates quadrature in a stipulative band scope, The phase shiftnetwork that is made in accordance with the design data is tested. The test results illustrate thathis network has small phase-shift error and good performance and meets the demand for single-band stereo broadcasting systems.
