| 31. | The intent was to develop an alternative receiver circuit that required fewer tuned circuits than the superheterodyne receiver.
|
| 32. | Changing the DC voltage across the varactor changes its capacitance, which changes the resonant frequency of the tuned circuit.
|
| 33. | One of the windings of the transformer had a variable capacitor connected across it to make a tuned circuit.
|
| 34. | This reduced the impedance loading of the tuned circuit, as well as improving the impedance match with the detector.
|
| 35. | The back shunt was a second tuned circuit consisting of an inductor, a capacitor, and load resistor in series.
|
| 36. | The antenna is an integral part of the tuned circuit and its reactance contributes to determining the circuit's resonant frequency.
|
| 37. | While stubs function as resonant circuits, they differ from monotonically with frequency after resonance as in a lumped tuned circuit.
|
| 38. | In the RF designs shown on this page, a tuned circuit is between the anode and the high voltage supply.
|
| 39. | Fractal inductors and fractal tuned circuits ( fractal resonators ) were also discovered and invented simultaneously with fractal element antennas.
|
| 40. | They typically have a long, low appearance, with a flip-up lid for access to the vacuum tubes and tuned circuits.
