Preparation of analogue signals includes considerations of filter amplitude attenuation and sampling rate in order to avoid aliasing errors,filter phase lags and time delays.Sampling and digitising considerations include pre-sampling amplification of signals to minimize digitising errors; number of bits per one sample; number of samples per one cycle; sample and hold amplifiers; and time-wise spacing of samples.Considerations for additional phaseless digital filtering include selections of pass-bands and stop-bands,the attenuation and allowable ripple in each,and corrections of filter phase lags.Each of these factors shall be considered in order to achieve a relative overall data acquisition accuracy of±0.5per cent.
专业知识不过硬,苦恼中,在知道里看到过很牛的翻译,只好来此求助了。

模拟信号的准备包括过滤振幅衰减的考虑和采样率,以避免混淆的错误,过滤器和相位滞后时间延误.采样和数字化的考虑包括前采样的信号放大,以减少数字化的错误;每一个样本的位数;数目与每一个周期样本;采样保持放大器和时间上的样品间距.额外phaseless数字滤波思考包括传递带的选择,停止波段的衰减以及在每个允许纹波和过滤相更正滞后.这些因素都应当考虑,以实现一个相对全面的数据采集精度± 0.5per百分之.
