Abstract
The disclosure teaches a reconfigurable parameter filter of the type useful in radar ESM systems. The filter has first and second sections adapted to be supplied with first and second binary numbers, respectively. Each section consists of upper and lower limit storage registers and upper and lower limit comparators, the comparators being coupled to an AND gate and responsive to the respective binary number to enable the AND gate if the value of the signal lies within the window set by the storage registers. The two sections can operate on two independent data words or can be coupled to act as a unit on one data word under the control of a mode selecting circuit. As a result the same standardized circuit module can process either one high precision parameter number or two low precision parameter numbers.
