Power Spectral Density Formula
The following formula is used to calculate the Power Spectral Density.
PSD = P / BW
- Where PSD is the Power Spectral Density ( )
- P is the total signal power
- BW is the total bandwidth
How to Calculate Power Spectral Density?
The following example problems outline how to calculate Power Spectral Density.
Example Problem #1:
- First, determine the total signal power .
- The total signal power is given as: 40.
- Next, determine the total bandwidth .
- The total bandwidth is provided as: 10.
- Finally, calculate the Power Spectral Density using the equation above:
PSD = P / BW
The values given above are inserted into the equation below:
PSD = 40 / 10 = (4 )
Example Problem #2:
For this problem, the variables needed are provided below:
total signal power = 75
total bandwidth = 20
This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.
PSD = P / BW = ?
