Aikataajuusesitys
Aikataajuusesitys, often translated as time-frequency representation, is a mathematical tool used to analyze signals that vary over time. It allows us to see how the frequency content of a signal changes as time progresses. Unlike a simple frequency spectrum, which shows the overall frequencies present in a signal, an aikataajuusesitys provides a two-dimensional depiction where one axis represents time and the other represents frequency. The intensity or color at any point on this representation indicates the strength of a particular frequency at a particular time.
Common methods for creating aikataajuusesity include the short-time Fourier transform (STFT), the wavelet transform, and the
Aikataajuusesity is widely applied in various fields. In audio processing, it's used for tasks like speech recognition,
