Time Domain and Frequency Domain Frequency domain: measured bySpectrum Analysiszer Tells us how properties (amplitudes) change over frequencies: Time Domain: measured byOscilloscope Tells us how properties(such as Amplitude(Power), Phase, and so on) change over time: ...
Frequency vs. Time Domain频域与时域 时域是指时间域,频域是指频率域。时域和频域是信号的基本性质。 为了理解振荡器中相位噪声和相位抖动之间的联系,我们必须首先理解抖动是在时域测量的,相位噪声是在频域测量的。 下图说明了它们各自域的度量。 The Relationship Between Time and Frequency ...
This chapter is concerned with representation of turbulent flow in both time and frequency domains. The discrete Fourier transform is introduced as a technique to transform a turbulence signal, such as a component of the velocity vector field, from the time domain to the frequency domain and vice...

vibration is expressed in positive numbers, with the peak amplitude as a measure of deviation from its central value. The same signal can also be displayed in a power versus frequency format. This would be displayed on a spectrum analyzer, which is capable of both time and frequency ...
