How do you find the harmonics of a signal?

Each harmonic frequency (f_n) is given by the equation f_n = n • f₁ where n is the harmonic number and f₁ is the frequency of the first harmonic.

What is spectral analysis technique?

Spectral analysis is a technique that can be used for the kinetic analysis of dynamic positron emission tomography scans at the voxel level. It is based on the definition of basis functions to describe the expected kinetic behavior of the tracer in the tissue.

What does spectral analysis tell us?

Spectral analysis is a technique which estimates the power. of a signal at different frequencies.

How signal processing is used for spectral analysis?

Spectral analysis is the process of estimating the power spectrum (PS) of a signal from its time-domain representation. Spectral density characterizes the frequency content of a signal or a stochastic process.
