On a higher level, if we assess a succession of numbers, x1, x2, x3, . If you are adding all numbers from a set together, you can refer to the result as "sum total", unlike if you add together only a part of the sequence. The number below Σ is known as the lower limit whereas the number above it is the upper limit. For example, if the lower limit is 1 and the upper limit is 10, this means that the sum operation is to be performed by replacing the variable (e.g. What's the best way to compare two DFT codes? It is called Sigma notation because the symbol is the Greek capital letter sigma: Σ.
