What is time domain analysis used for?
Time domain analysis provides the transitory response of a system to be analyzed, and it permits a better understanding of the flow of both mechanical and electrical energies. In general, this includes wave propagation, the structural changes of a system, and electric potential generated by external excitations.
What is time frequency domain analysis?
Frequency-domain analysis is widely used in such areas as communications, geology, remote sensing, and image processing. While time-domain analysis shows how a signal changes over time, frequency-domain analysis shows how the signal's energy is distributed over a range of frequencies.
How is time domain a signal analyzer?
A spectrum analyzer takes an analog input signal—a time-domain signal—and uses the Fast Fourier Transform (FFT) to convert it to the frequency domain. The resulting spectrum measurement shows the energy of each frequency component at each point along the frequency spectrum.
