Applications of Power Spectral Density
- Signal Processing: PSD concept is used to extract relevant information from the signals for pattern recognition and various machine learning techniques. PSD is also used in the field of telecommunication for signal classification. it is also used for noise analysis as well from the PSD distribution.
- Communications: In the field of communication PSD is used for optimizing spectral efficiency and it also helps to characterize frequency selective fading of communication channels.
- Audio Processing: It is used for noise reduction and for equalizing in the field of audio processing.
- Biomedical Signal Processing: PSD analysis of the Electroencephalography (EEG) helps one to study about the brain activity and PSD can also be used for measuring heart rate variability.
- Environmental Monitoring: PSD analysis of environmental sounds could help one understand about different wildlife habitats and for identifying different species.
Power Spectral Density
In terms of electronics, Power is defined as the total amount of energy that is getting transferred or converted per unit measurement of time, or in general terms Power is defined as the strength or the intensity level of the signal. Power is generally measured in watts (W).
