ABSTRACT:
A RF tuning circuit according to this invention is composed of one tuned transformer (T.sub.1) at least and an untuned transformer (T.sub.2) so interconnected that the outputs from the respective transformers add up opposite in phase on that side of the resonant frequency of the tuned transformer where the image signal frequency is present and in phase on that side thereof where the image signal is absent and that the output amplitude levels of the respective transformers become equal at the image signal frequency corresponding to a particular receiving frequency as the resonant frequency is varied in response to the receiving frequency.
