What are the output values averange The averange delay Jitter It tells us the averange variation of the delay The math behind Precise jitter $$ \sqrt\frac{(num_0-Avg)^2+...+(num_n-Avg)^2}{N-1} $$ Less precise jitter $$ \sqrt\frac{(num_0-Avg)^2+...+(num_n-Avg)^2}{N} $$ Usage To call the program you must be in the same directory as the file. To use it: python3 jittercalc.py <num1> <num2> ... <numN> There is no limit on how many values you can input.
