वेक्यूम-त्यूब इसके अंग्रेजी अर्थ का उदाहरण

The original circuitry was developed using two vacuum tubes and a photocell to search and follow a light.

The circuit utilizes the non-linear cathode to control grid conduction characteristic and the amplification factor of a vacuum tube.

Invented by Lee De Forest around 1912, it was used as the detector (demodulator) in the first vacuum tube radio receivers until the 1930s.

First use of a resistance to discharge the grid condenser in a vacuum tube detector circuit may have been by Sewall Cabot in 1906.

The computer, dubbed the 901, was a vacuum tube computer.

Charlotte's first mission to France is to deliver radio vacuum tubes.

Year of birth missing (living people) The EL34 is a thermionic valve or vacuum tube of the power pentode type, first made in 1949.

According to the data sheets found in old vacuum tube reference manuals, a pair of EL34s with 800 V plate voltage can produce 90 watts output in class AB1 in push–pull configuration.

List of vacuum tubes.

A major defect of the TRF receiver was that, due to the high interelectrode capacitance of early triode vacuum tubes, feedback within the RF amplifier stages gave them a tendency to oscillate, creating unwanted radio frequency alternating currents.

By the 1930s, advances in vacuum tube manufacturing had yielded the tetrode, which had reduced control grid to plate (Miller) capacitance.

Sportspeople from Madison, Wisconsin A tube caddy is a type of carrying case used for storing and transporting vacuum tubes.
