ブライトパルス加算回路。 A first transistor whose base is supplied with a television signal, a second transistor which forms a differential amplifier together with this first transistor, and an emitter connected to the base of this second transistor and whose base is supplied with a bright pulse. The differential amplifier includes a third transistor supplied and a fourth transistor whose collector is connected to the base of the third transistor, and controls conduction/non-conduction of the fourth transistor. A bright pulse addition circuit characterized in that it stops and executes an operation of superimposing a bright pulse on the television signal.
