Abstract

PURPOSE:To obtain the low frequency output equal to the difference between two oscillated frequencies easily by obtaining AND of two oscillator circuits which oscillate on frequencies near to each other. CONSTITUTION:Oscillator circuits 10 and 10a oscillate on frequencies near to each other, and have the output taken out from collectors of output transistors Tr2 and 2a respectively and connected to the base of Tr11. The emitter of this Tr11 is connected to the negative pole of DC power source 3, and the collector is connected to the positive pole of power source 3 through load resistance 12, thereby forming logical operation circuit 3. At a result, AND of both oscillator circuits can be obtained at the collector of Tr11, so that the low frequency output equal to the difference between two oscillated frequencies can be obtained easily.
