A harmonic is a wave orsignalwhose frequency is an integral (whole number) multiple of the frequency of the same reference signal or wave. As part of the harmonic series, the term can also refer to the ratio of the frequency of such a signal or wave to the frequency of the reference s...
aSimple harmonic signals are the simplest and most important periodic signals.Any periodic signal can be expressed by simple harmonic signal.The bridge contacts them is the Fourier Series,therefore the Fourier Seriesis the theoretical basis of periodic signal. 简单的泛音信号是最简单和最重要的周期性信...

Elliptic filters are chosen when the application demands aggressive out-of-band signal suppression. Bessel: Bessel filters have a more gradual roll-off compared to Butterworth and Chebyshev filters, but they provide better phase linearity across the passband. This is particularly important in ...
Amplifier – Gains the signal from the frontend and inputs into the shaker, depending on size of shaker, size of the test item and target vibration levels, a high level of voltage or current may be required. Shaker – Electrodynamic or hydraulic device that has a moving mass to recreate vi...
The first specification to investigate is the sensitivity of a receiver. The main limiting factor in any radio receiver is the internal noise that is generated. For many radio communications applications either the signal to noise ratio or the noise figure is used....
The acquired data is sent to a computer and analyzed with Order Analysis software. Example of Order analysis results of a running machine. Left figure: a spectrogram of vibration values for the first 10 harmonic orders, measured between 1000 rpm and 3000 rpm. Right figure: extracted values for...
