采用多相调制可以获得单边带信号,宽带相差网络是其重要部件。本文依据契比雪夫逼近原理,运用椭圆函数变换得到具有偏差为任意小的0<β<π宽带相差网络,文末附有实例。
Multi-phase modulation can be used to obtain single-sideband signal, wideband phase difference network is an important part. According to the Chebyshev approximation principle, this paper uses the elliptic function transform to get a broadband difference network with 0 <β <π with arbitrary small deviation.
