Time domain (time domain -time domain)
- independent variable is the time, i.e., the horizontal axis represents time and the vertical axis is the change of the signal (amplitude) . The dynamic signal x (t) is the function describing the values of signals at different times.
A frequency domain (frequency domain - frequency domain)
- argument is the frequency, i.e., the horizontal axis represents frequency , and the vertical axis is the frequency of the signal amplitude (amplitude ), refers to the magnitude of the voltage signals, it is often said spectral FIG.
analysis
Domain analysis parameters is a function of the time t, i.e. y = f (t),
time-frequency domain analysis, parameters w, i.e. y = F (w) may be converted mutually therebetween. Time domain function by a Laplace transform or Fourier frequency domain function becomes.
