Abstract : The invention relates to a bistable frequency fuze system and more particularly to a bistable frequency fuze system wherein the oscillator is made to provide two widely separated frequencies to prevent the use of jamming techniques on the fuze. The invention provides a circuit which significantly reduces VT (variable time) fuze vulnerability to repeater, hunt-lock-on, sweep and/or barrage jamming signals. The accomplishment of this is based on the principle of switching the r-f oscillator frequency between two stable but widely separated operating frequencies.
