回路。[Claims for Utility Model Registration] <1) In an indicator circuit for operating a stereo indicator of an AM stereo receiver, a discriminating means for discriminating the presence or absence of a difference signal, and an indicator for operating the indicator using the output of the discriminating means. An AM stereo indicator circuit characterized in that it is provided with lighting means. (2) The indicator lighting means includes a carrier wave detecting means for detecting a carrier wave, an AND means for logically multiplying the output of the carrier wave detecting means and the output of the discriminating means, and storing the output of the AND means. The AM stereo system according to claim 1 of the utility model registration claim, characterized in that it has a storage means.
indicator circuit. (3) The AM stereo signal indicator circuit according to claim 2, wherein the storage means is reset when the carrier wave disappears. (4) The AM stereo indicator circuit according to claim 2, wherein the storage means is reset after a predetermined time has elapsed from the time when the difference signal disappears.
