基带分析 meaning in English

baseband analyzer

Secondly , the possibility and efficiency of applying the spectrum analysis usually used in vibration testing for rotating machine to operation vibration of hv circuit breaker is discussed , the paper goes deeply into this new method and idea , especially the zoom spectrum algorithm . by comparing normal fft , zoom - fft ( zfft ) and chip - z transform ( czt ) on principle , arithmetic , characteristic and amount of calculation , czt is proved superior and thus selected
论文深入研究了细化频谱分析技术，对比分析了基带分析和常用的选带细化分析算法的原理、方法、运算量和特点，在此基础上，选定线性调频z变换（ czt ）作为断路器操动机构振动信号频谱分析的细化方法。
