Abstract

PURPOSE:To receive the electric wave of another broadcasting system by further frequency-converting an original intermediate frequency at a low band receiving time when the different electric waves are received to the broadcasting system. CONSTITUTION:The tuner of a super heterodyne system includes input circuits 1 and 7, high frequency amplifying circuits 2 and 8, interstage circuits 3 and 9, local oscillating circuits 4 and 10, frequency mixing circuits 5 and 11 and an IF circuit 6 in an enclosure. Further, in this enclosure, an IF converter 12 is provided to frequency-convert the original intermediate frequency at the low band receiving time. This IF converter 12 is composed of a local oscillating circuit 13 for IF conversion, an IF frequency mixing circuit 14 and an IF circuit 15.
