This paper analyzes usual measuring errors caused by inconsistency of the input signal pulse verge and strobesignal verge in frequency measurement. It sets forth an effective solution.
研究频率测量过程中输入信号的脉冲边沿与测量设备的闸门信号边沿不一致造成的频率测量误差。
2
The strobesignal is not commonly associated with the signal tested.
计数式频率计的选通门一般与被测信号是不相关的。
3
PC sent signal via print control port and STROBE, encoder generated choosing signal and sent it to P3.2-end of single-chip to form interrupt.
