Offset current is especially significant when measuring low currents if the magnitude of the offset is comparable to the low current being measured.
在测量小电流时，如果偏移电流的幅值与被测小电流相当，偏移电流就尤其明显。
It describes clearly the software of vector signal demodulation, including the frequency offset calculation, magnitude and group-delay compensate, and pulse shaping filter.
在软件方面，详细介绍和分析了矢量信号解调分析软件设计与实现，其中包括载频频偏计算、幅度和群时延补偿、脉冲成形滤波器设计等。
