The phase detecting error caused by local oscillator frequency drift and non-synchronization of measurement signal and gate signal is eliminated and the measurement speed is improved at the same time.
该方法可以有效的消除因本振信号频率漂移及闸门信号与被测信号的非同步引起的测相误差,同时提高了测量速度。
The jitter error brought in by the aperture jitter increases as the frequency increase of the input signal in high speed data acquisition systems, thus it degrades the system's SNR.
结果表明,孔径抖动引起的孔径误差随着高速数据采集系统输入信号频率的升高而增大,由此将引起系统信噪比的下降。
It takes both signal error and time error in consideration, avoids complicated operations such as division, square root, etc. So it has high precision and speed.
该方法既考虑信号误差,又考虑时间误差,避免除法、开方等复杂运算,精度高、速度快。
