taajuuskuvaa
Taajuuskuva (frequency spectrum) is a graphical representation of the frequency components that make up a signal. It is commonly used in signal processing, audio engineering, and telecommunications to analyze and understand the frequency content of a signal. The x-axis of a frequency spectrum plot represents frequency, typically in Hertz (Hz), while the y-axis represents the amplitude or power of each frequency component.
There are several types of frequency spectra, including:
1. Amplitude spectrum: Shows the amplitude of each frequency component.
2. Power spectrum: Shows the power of each frequency component, which is the square of the amplitude.
3. Phase spectrum: Shows the phase of each frequency component relative to a reference signal.
Frequency spectra can be obtained using various techniques, such as the Fourier transform, which converts a
Frequency spectra are widely used in applications such as audio analysis, speech recognition, image processing, and
