Enter the total number of information bits and the total number of overhead bits into the calculator to determine the transmission efficiency.

Transmission Efficiency Formula

The following equation is used to calculate the .

Et = IB / (IB+OB)

  • Where Et is the transmission efficiency
  • IB is the number of information bits (bits)
  • OB is the number of overhead bits (bits)

To calculate the transmission efficiency, divide the quantity of information bits by teh total number of bits.

What is a Transmission Efficiency?


Transmission efficiency measures the ratio of bits transferred that have information relative to the total amount of bits transmitted by a system.

How to Calculate Transmission Efficiency?

Example Problem:

The following example outlines the steps and information needed to calculate Transmission Efficiency.

First, determine the number of information bits. In this example, the number of information bits is 500.

Next, determine the number of overhead bits. In this case, the number of overhead bits is 100.

Finally, calculate the transmission efficiency using the formula above:

Et = IB / (IB+OB)

Et = 500 / (100+500)

Et = .833 = 83.3%
