Operating at real-time data rates, a hardware network generates a signal which closely approximates the Mth largest of a set of R input data signals. The operational basis of this network is a comparison (121-127) between the input data (101-107) and a monotonically-scanning reference function (110). At that point (140, 150, 160) when the lower (R-M+1) of the inputs have been equaled by an increasing reference, the reference has become the same as the Mth-largest and is used (119b, 165, 170, 175) as the filter output. Analogous operation is achieved with a decreasing reference. When the number of inputs is odd and M is made equal to ((R+ 1)/2), the network becomes a real-time median filter. |
