Characteristics of Power Spectral Density (PSD)
- It describes the power distribution or the strength of the signal over a range of frequencies.
- The shape of the plot gives an important characteristics like narrower peak describes that most of the power of the signal is concentrated at this particular frequency whereas broader peak describes that most of the power of the signal is distributed over a wide range of frequencies.
- The peak value in the plot represents the frequencies having higher or greater power level.
- It also helps in determining the bandwidth of the signal which refers to the range of the frequencies over which the energy is distributed. The plot having wider bandwidth denotes that the signal energy is distributed over wide range of frequencies.
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).
