Abstract
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) for suppressing parsitic oscillations between ground and a junction (J) of a parallel LC resonator of the local oscillator.
