FIR and IIR are digital filters that are commonly used in digital signal processing. There are only a few components that make up these filters, but these components can be arranged in various ways to make complicated filters for use in digital signal processing.
In some statistical analyses, the median is a better predictor of the expected value for a set of observations than the mean (average). To calculate the median, in the simplest terms, if you have an odd number (n) of items in an ordered set, the median is the value where (n+1)/2 is the row containing the median value. If there is an even number of rows, the value is the average (mean) of the two values appearing in the n/2 and the 1+n/2 rows.
2) If n is odd, median is the middle value i.e. X(n+1)/2 3) If n is even, median is (Xn/2 + X(n+1)/2) / 2 You may refer below link for better understanding on how to calculate median: http://verticalhorizons.in/how-to-calcul...
