grid leak उदाहरण वाक्य
उदाहरण वाक्य
अधिक: आगे- A grid leak resistor and capacitor unit from 1926.
- Having the grid leak resistor, even in the Megohm range, shunting signal to ground loads the received signal.
- The use of grid leak bias competed with use of a so-called C battery for providing a fixed negative voltage on the grid.
- Until the early 1930s this was common practice in valve ( tube ) radio sets but was largely superseded by grid leak resistors or voltage divider biasing.
- In better sets, the grid leak detector's output fed-after filtering out the RF-an audio amplifying valve, or occasionally more than one.
- One potential disadvantage of the grid leak detector is that the input impedance of the detector may be affected by the need to self bias the detector tube with grid current.
- The grid leak detector circuit output, often taken from the plate of the detector tube, may require additional filtering to remove remnants of the carrier portion of the received signal.
- In simple one-valve sets, the grid leak detector directly drove the headphones, since it produced enough audio frequency output from local ( and some distant ) stations as well as radio frequency.
- Plate detectors have the advantage in that they isolate the detector load from the input circuit more effectively and may be employed where sensitivity is thought to be otherwise compromised by a grid leak or diode detector circuit.
- In the auto-bias configuration, the " operating point " is obtained by setting DC potential of the input grid at zero volts relative to ground via a high-value " grid leak " resistor.
