What is signal in time domain?
Time domain signal processing analyzes the input signal depending on the waveforms observed over a period of time. Time domain techniques emphasize the amplitude variation in a specific time period. This has many applications in speech processing and heavy vehicle classification.
What happens when you square a signal?
Squaring your signal is multiplying it with itself. Multiplication in frequency domain is convolution in time domain. So you're correlating the signal in time domain with its time-inverse.
How do you represent signal in time and frequency domain?
Time domain representation – In frequency domain, a signal is represented by its frequency spectrum. To obtain frequency spectrum of a signal, Fourier series and Fourier transformation are used. Fourier series is used to get frequency spectrum of time-domain signal, when the signal is periodic function of time.
How do you convert a signal from time domain to frequency domain?
Relationship between the Time Domain and Frequency Domain
Thus, given the signal x(t) and the unit impulse response h(t), one can either directly calculate the response y(t) via convolution in the time domain, or one can apply the Fourier transform to x(t) and y(t) to move into the Fourier domain.
