hexode meaning in Hindi

Examples

1. For example, the 2F21 is not an actual hexode, but a pattern generating monoscope tube.
2. Thus a pentagrid radio could easily be converted to a triode-hexode without any other circuit modifications.
3. The hexode contains two such grids, one for a received signal and one for the signal from a local oscillator.
4. It was not long before the triode and hexode structures were placed in the same glass envelope-by no means a new idea.
5. Following pressure from the UK manufacturers, the BVA were compelled to relax the rules and the UK started to adopt triode-hexode mixers.
6. Other tubes with multiple grids beside the pentode, such as the hexode and pentagrid converter tube, have been be used to make similar negative transconductance oscillators.
7. The 2G21 is a subminiature Triode-Hexode, with a maximum anode ( plate ) current of some 0.2 milliamps and a maximum voltage of 45 volts.
8. A typical such " orbital beam hexode " was the RCA 1630, introduced in 1939 . Because the heavy electron current in such tubes damaged the dynode surface rapidly, their lifetime tended to be very short compared to conventional tubes.
9. The UK manufacturers were initially unable to use this type of mixer because of the MOV, successfully enforced the cartel rules against the German Lissen company in 1934 when they attempted to market a radio in the UK which had the triode-hexode mixer.
10. The triode grid was usually internally connected to the hexode grid 3, but this practice was dropped in later designs when the mixer section operated as a straight IF amplifier in AM / FM sets when operating on FM, the mixing being carried out in a dedicated FM frequency changing section.
