| 1. | A rectifier and a filter capacitor were connected directly to the mains.
|
| 2. | LEDs are connected in parallel with the 10 ?F electrolytic filter capacitor.
|
| 3. | In old radios, the filter capacitors often fail, resulting in hum and distortion.
|
| 4. | The name illustrates the charging of the filter capacitor at the peaks of the AC voltage.
|
| 5. | Because areas near Niagara Falls had 25 Hz power, some Canadian sets had slightly larger filter capacitors.
|
| 6. | This meantime is defined by the grid side located filter capacitors have been discharged by the installed bleeding resistors.
|
| 7. | In some CRTs the aquadag coating performs a third function, as a filter capacitor for the high-voltage anode supply.
|
| 8. | The typical anode supply was a rectifier, perhaps half-wave, a choke ( inductor ) and a filter capacitor.
|
| 9. | The frequency of these pulse trains is then varied to produce the desired output voltage with the aid of the output filter capacitor.
|
| 10. | Although the capacitance is small, around 500 pF, due to the low anode current it is sufficient to act as a filter capacitor.
