DUAL MODE TUNING ARRANGEMENT

摘要

In a local oscillator for a tuning arrangement for both TV and FM signals there is substantial risk of parasitic oscillation. A special provision is disclosed for effectively reducing this risk. The special provision is a connection of a damping resistor (R 1 a) for suppressing parsitic oscillations between ground and a junction (J 2 ) of a parallel LC resonator of the local oscillator.
