1. The Poulsen arc converter has a tuned circuit connected across the arc. 2. For a tuned circuit , inductance is used to provide a frequency-selective circuit. 3. A tuned circuit is connected between the electrode and the cathode. 4. In this role the circuit is often referred to as a tuned circuit . 5. All the tuned circuits need to track to keep the narrow bandwidth tuning. 6. Electrical resonance of tuned circuits in radios allow individual stations to be selected. 7. Superheterodyne receivers allow use one or more fixed intermediate frequency tuned circuits for selectivity. 8. Bandwidth of tuned circuits and reduce the circuit s frequency selectivity, or Q factor. 9. It is a parallel tuned circuit containing inductance and capacitance. 10. Receivers could be made with a tuned circuit , a crystal detector, and a headphone.
