本文引入“非零频阶跃的希尔伯特变换”,并以收录机走带子稳性和齿轮箱振动为例用于提取时域压缩的包络和相位信号,结果表明,这种变换对这一类信号的处理是高效的。
In this paper, the “Hilbert transform of non-zero-frequency step” is introduced in this paper. Taking the tape transport stability and gearbox vibration as an example, the envelope and phase signals of time-domain compression are extracted. A class of signal processing is efficient.
