Enter the total signal power (watts) and the bit rate (bits per second) into the Energy Per Bit Calculator. The calculator will evaluate the Energy Per Bit.
Energy Per Bit Formula
The following two example problems outline the steps and information needed to calculate the Energy Per Bit.
Eb = SP / BR
Variables:
- Eb is the Energy Per Bit (joules)
- SP is the total signal power (watts)
- BR is the bit rate (bits per second)
To calculate the energy per bit, divide the total signal power by the bit rate.
How to Calculate Energy Per Bit?
The following steps outline how to calculate the Energy Per Bit.
- First, determine the total signal power (watts).
- Next, determine the bit rate (bits per second).
- Next, gather the formula from above = Eb = SP / BR.
- Finally, calculate the Energy Per Bit.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
total signal power (watts) = 50
bit rate (bits per second) = 30
Eb = SP / BR = ?
