tidfrekvensdomæne
Tidfrekvensdomæne refers to the representation of a signal or data where both time and frequency are explicit variables. This is in contrast to the time domain, where only time is considered, or the frequency domain, where only frequency is considered. In the tidfrekvensdomæne, one can analyze how the frequency content of a signal changes over time.
This type of analysis is particularly useful for non-stationary signals, which are signals whose frequency characteristics
Common techniques for transforming a signal into the tidfrekvensdomæne include the Short-Time Fourier Transform (STFT) and
