| 41. | Tetrode transistors ( whether bipolar junction or field-effect ) do not exhibit improvements of such a great degree.
|
| 42. | They usually had two type 48 power tetrodes that could operate with B + voltages as low as 28 volts.
|
| 43. | Gerard van Tetrode donated land in 1310 in the centre of Haarlem to build St . John's monastery.
|
| 44. | The pentode was invented in 1926 by Bernard D . H . Tellegen and became generally favored over the simple tetrode.
|
| 45. | In other tetrodes one of the grids is a control grid, while the other may have a variety of functions.
|
| 46. | To produce the short pulses of signal, the transmitter consisted of Hartley oscillators feeding a pair of tetrode amplifier tubes.
|
| 47. | When a tetrode or pentode is used, the screen grid voltage is usually about one-half the plate voltage.
|
| 48. | In 1912, Tetrode developed the Sackur Tetrode equation, a quantum mechanical expression of the entropy of an ideal gas.
|
| 49. | In 1912, Tetrode developed the Sackur Tetrode equation, a quantum mechanical expression of the entropy of an ideal gas.
|
| 50. | In 1926, Philips invented a technique of adding yet another grid to combat the secondary emission that the tetrode suffered from.
