本文研究了延迟线具有任意线性相频特性时梳状滤波器的幅频特性和相频特性。弥补了有关文献只分析特定延时条件下的幅频特性的不足。本文提出了可给延迟线的生产和调整带来方便、可望克服大面积行蠕动现象的一种新的PAL解码方案(PAL_(MS)),并全面论证了它的各种主要性能。
In this paper, the amplitude-frequency characteristics and phase-frequency characteristics of a comb filter with an arbitrary linear phase-frequency characteristic of a delay line are investigated. Make up for the lack of amplitude and frequency characteristics of the relevant literature to analyze only the specific delay conditions. This paper presents a new PAL decoding scheme (PAL_ (MS)) which can bring convenience to the production and adjustment of delay line and is expected to overcome the peristaltic behavior of large area lines, and fully demonstrates its various key performance.
