本文讨论了限制脉冲调制乘法器静态及动态品质进一步提高的几项主要误差,提出了减小这些误差的一些方法.这些方法的实现,可将乘法器的静态误差电压减小到0.1伏(满刻度变化为±100伏),并将两个乘量通道的频率特性在100周时的相移减小到2°.
This article discusses several major errors that limit the further improvement of the static and dynamic quality of a pulse-modulated multiplier, and suggests ways to reduce these errors. These methods reduce the quiescent error of the multiplier to 0.1 volts The scale changes to ± 100 volts) and the phase shift of the frequency characteristics of the two multipath channels is reduced to 2 ° at 100 weeks.
