AUDIO-SIGNAL GENERATOR Russian patent published in 1996 - IPC

FIELD: equipment of every-day use, warning devices. SUBSTANCE: audio-signal generator uses subtracter 1, whose complementing output is connected to the output of pulse generator 2, output of the branch on zero is connected to the complementing input of flip-flop 3, and the set inputs - to the outputs of storage 4, whose inputs are connected to the outputs of binary counter 5, whose reset input is connected to input terminal 6; the output of flip-flop 3 is connected to output terminal 7; the reset inputs of subtracter 1 and flip-flop 3 are connected to input terminal 6, and the complementing input of binary counter 5 and the input of preliminary setting of subtracter 1 are connected to the complementing input of flip-flop 3. EFFECT: improved design. 2 dwg
