sampling frequency ˈsæmplɪŋˈfri:kwənsi 短语⁹⁶⁶⁷⁷⁺⁶
基本英英例句例句
采样频率
Noun:
telecommunication the frequency of sampling a continuously varying signalThis is equivalent to requiring that the Nyquist frequency be strictly greater than the bandwidth or the signal.一个频率正好是采样频率一半的正弦信号，通常会混叠成另一相同频率的正弦信号，但它的相位和幅度改变了。
The relation between decomposition error and sample frequency was revealed and it was also proved that increasing the sample frequency can effectively reduce the error.研究结果揭示了分解误差和采样频率的关系，验证了提高采样频率可以有效地降低分解误差。
A false signal in telecommunication links from beats between signal frequency andsampling frequency.假信号信号频率和取样频率之间的拍子在无线电通信线路产生的假信号。 For bandpass signal under digital quadrature sampling, there is spectrum shifting. Although the sampling frequency satisfies the sampling theorem, it may cause spectrum aliasing.
在数字正交采样中，带通信号存在频谱迁移问题，虽然满足带通信号的采样定理，仍可能产生频谱混叠。 cnki |
