zero phase shift

in electronics and communications, pertaining to signals that have a zero phase shift relative to each other.

在电子技术和通信技术中，用来说明各个信号相互之间没有相位差。

A phase shift converter can achieve zero voltage switching on the leading leg and zero current switching on the trailing leg by utilizing the reverse avalanche characteristics of IGBT. This circuit can provide low switching losses when IGBT is operating in high switching frequency.

利用IGBT的反向雪崩特性，实现伪相移变换器前臂零电压、尾臂零电流开关，使IGBT可在高开关频率下运行，且降低了开关损耗。

The Binary phase shift keying ( BPSK) and Mary amplitude shift keying ( MASK) are widely used in radar systems, their elliptic covariance do not equal zero, are noncircular signals.

二进制相移键控（BPSK）和幅度调制（MASK）等信号是雷达系统中常用的信号，这种调制信号的椭圆协方差矩阵不为零，被称为非圆信号。

Dispensing with phase shift and sampling a number of images, the introduction of wavelet transform into digital holography can directly eliminate zero-order diffraction image.

将小波变换引入数字全息，可直接消除零级衍射像，无需相移，也不需要采集多幅图像；
