The tach signal is sampled synchronously with the vibration signals. The integral period sampling is implemented by software in the forthcoming process.
对鉴相信号与振动信号进行同步采样，而对振动信号的整周期截取则利用软件实现。
The integral period sampling, which is realized by realtime frequency calculation and voltage capture function of IC chip, is necessary for precise digital signal processing.
借助芯片的捕获功能，计算信号的实时频率，实现了整周期采样，保证了数字信号处理的精度。
The fast Fourier transform (FFT) will bring on higher error under nonsynchronous sampling and truncated non-integral period, thus more accurate interharmonic parameter values cannot be obtained.
快速傅里叶变换在非同步采样和非整数周期截断的情况下存在较大误差，无法获得较精确的间谐波参数值。
