A television apparatus (100) is switchable to a radio receiver mode. The radio signal is processed in a picture processing path of the television apparatus, transformed to a predetermined auxiliary intermediate radio carrier frequency (fIR) within the picture pass band of the picture processing path, such that the relationship fIR = fref,i - fD is satisfied, fref,i being an intrinsic reference frequency of a PLL reference signal generator, and f¿D< being the frequency distance between a predetermined intermediate picture carrier frequency (fIP) and a predetermined intermediate sound carrier frequency (fIS) for television signals. |
