Here is how the Coding Redundancy equation looks like.

99.919 = (1 - (\frac{1.13}{420 \cdot \log 2 (10)})) \cdot 100

99.919 = (1 - (\frac{1.13}{420 \cdot \log 2 (10)})) \cdot 100

99.919 = (1 - (\frac{1.13}{420 \cdot \log 2 (10)})) \cdot 100

R ηc = (1 - (\frac{1.13}{420 \cdot \log 2 (10)})) \cdot 100

Next Step Prepare to Evaluate

∴

R ηc = (1 - (\frac{1.13}{420 \cdot \log 2 (10)})) \cdot 100

Next Step Evaluate

∴

R ηc = 99.9190085964047

LAST Step Rounding Answer

∴

R ηc = 99.919

How to Evaluate Coding Redundancy?

Coding Redundancy evaluator uses Code Redundancy = (1-(R-Ary Entropy/(Average Length*log2(Number of Symbols in Encoding Alphabet))))*100 to evaluate the Code Redundancy, The Coding Redundancy occurs when a character or group of characters in a code word can be partially or completely deduced from the remaining characters of the code word. Code Redundancy is denoted by R_ηc symbol.

How to evaluate Coding Redundancy using this online evaluator? To use this online evaluator for Coding Redundancy, enter R-Ary Entropy (H_r[S]), Average Length (L) & Number of Symbols in Encoding Alphabet (D_s) and hit the calculate button.

FAQs on Coding Redundancy

What is the formula to find Coding Redundancy?

The formula of Coding Redundancy is expressed as Code Redundancy = (1-(R-Ary Entropy/(Average Length*log2(Number of Symbols in Encoding Alphabet))))*100. Here is an example- 99.91901 = (1-(1.13/(420*log2(10))))*100.

How to calculate Coding Redundancy?

With R-Ary Entropy (H_r[S]), Average Length (L) & Number of Symbols in Encoding Alphabet (D_s) we can find Coding Redundancy using the formula - Code Redundancy = (1-(R-Ary Entropy/(Average Length*log2(Number of Symbols in Encoding Alphabet))))*100. This formula also uses Binary Logarithm (log2) function(s).
