Taajuusdomainan
Taajuusdomainan, also known as frequency domain, is a mathematical concept used to analyze and represent signals in terms of their frequency components. Unlike the time domain, which represents signals as a function of time, the frequency domain represents signals as a function of frequency. This transformation is typically achieved using the Fourier transform, which decomposes a signal into its constituent frequencies.
The frequency domain is particularly useful in various fields such as signal processing, communications, and control
One of the key advantages of the frequency domain is its ability to simplify complex signals. By
However, the frequency domain also has its limitations. The Fourier transform assumes that the signal is periodic
