Two switching elements are cross-coupled in the standard bistable multivibrator arrangement. Two additional switching elements are added: one each in parallel with one of the switching elements forming the bistable multivibrator. The two wave forms under study are applied to the control gate of each of the additional switching elements. When both wave forms are in one state, the two additional switching elements are switched ON, effectively inhibiting bistable multivibrator action. The first wave form to change state results in its associated switching element switching OFF, which releases the bistable multivibrator circuit to assume the corresponding stable state, which observed differentially across the switching element forming the bistable multivibrator, is indicative of the wave form to first undergo transition. After the first wave form has undergone transition, the bistable multivibrator becomes insensitive to the subsequently occuring transition on the second wave form, and the circuit remains in the defined stable state until both wave forms again assume their previous state prior to transition, in which, once again, bistable multivibrator action is inhibited.
