Abstract

PURPOSE:To achieve a device which features a reduced drift of the channel selection voltage and an easy IC formation and in which the output receives no effect by the unevenness of the coupling parts as well as the dispersion of the center value of the automatic tuning circuit voltage for the channel selection device which is used for the TV receiver.
