Source Efficiency Solution

STEP 0: Pre-Calculation Summary

Formula Used

Source Efficiency = (Entropy/Maximum Entropy)*100
η_s = (H[S]/H[S]_max)*100
This formula uses 3 Variables

Variables Used

Source Efficiency - Source efficiency is the ratio of the amount of information that can be transmitted over a channel using a particular source to the total amount of information in the source.
Entropy - (Measured in Bit per Second) - Entropy is a measure of the uncertainty of a random variable. Specifically, it measures the average amount of information contained in each possible outcome of the random variable.
Maximum Entropy - (Measured in Bit) - The Maximum entropy is defined as states that the probability distribution which best represents the current state of knowledge about a system is the one with largest entropy.

STEP 1: Convert Input(s) to Base Unit

Entropy: 1.8 Bit per Second --> 1.8 Bit per Second No Conversion Required
