Abstract : The patent describes a system for eliminating interference and spurious responses from the output of a radio receiver which is being used as an accurate, carefully controlled test instrument. A signal under test is fed to parallel receivers, both receivers operating with the same local oscillator to produce outputs which are compared with an AND circuit. Matching signals must be presented to the AND circuit simultaneously in order for it to pass the test signal.
