frekvenciatérbeli
Frekvenciatérbeli, often translated as frequency domain, is a concept used in signal processing and other scientific fields to represent a signal as a function of frequency. Instead of looking at how a signal changes over time (the time domain), we analyze its constituent frequencies and their amplitudes. This transformation is typically achieved using mathematical tools like the Fourier Transform.
In the frequency domain, a complex signal is broken down into a sum of simpler sinusoidal waves
Analyzing signals in the frequency domain can reveal characteristics that are not easily observed in the time
