谱泄漏 meaning in Chinese

spectral leakage

Because massive harmonic interference in the electrical network , it causes signal - sampling to include the very big harmonic in the measurement system , for eliminating measurement result influence by harmonic , the paper has an in - depth study of fourier transformation harmonics analysis measurement principle , analysis the forming reasons of frequency spectrum leakage and railing effect during measurement , achieves phase locked loop and frequency multiplier technique to realize integer - period synchronous sampling and eliminate impact of frequency spectrum leakage and railing effect in the result of measurement , and investigates in depth theory on phase locked loop and frequency multiplier technique , gives the method of realizing phase locked loop and frequency multiplier technique
由于电网中存在大量的谐波干扰,导致测量系统中取样信号也含有很大的谐波,为了消除谐波对测量结果的影响,论文深入研究了傅立叶变换谐波分析法的测量原理,分析了测量中频谱泄漏和栅栏效应形成的原因,提出了采用锁相环倍频技术实现信号的整周期同步采样,消除频谱泄漏和栅栏效应对测量结果的影响,并对锁相环倍频技术的理论进行了深入研究,给出锁相环倍频技术的实现方法。
