You recorded some measurement data and you do not know if the data is periodic or not, or even worse, you do know that the data is NOT periodic. Can you still use the harmonic analysis and get meaningful results? Explain.

Solution

Yes,we can use harmonic analysis. If the signal is continuous non periodic signals we use Continuous

fourier transform and if it is discrete non periodic we use Discrete time Fourier transform.
