What were used for radios in 1960's?
-- information -- education -- entertainment -- news -- music -- drama -- business / commercial announcements -- aircraft communication -- military communication -- maritime communication -- international / propaganda broadcast -- navigation -- hobby Pretty much the same as today, when you think about it.
What is a cross coupled transistor?
A cross coupled transistor pair are used to increase the gain of the cell.
When a PNP transistor is connected in a circuit it can be used as a power amplifier because?
A PNP transistor has no advantage or disadvantage over an NPN transistor in its ability as an amplifier. Rather, the current-handling capacities of the transistor determine if it's usable as an amplifier.
What transistor can be used in enhancement mode?
MOSFET can be used in enhancement mode
Can fet be used as a transisitors?
No. The Field Effect Transistor is a different technology than the Bipolar Junction Transistor. That cannot substitute for one another.
Does a cathode ray tube resemble the tubes used in transistor radios?
Transistor radios have NO tubes. They have (guess what) transistors.
Where can someone purchase transistor radios online in bulk?
Someone can purchase transistor radios online in bulk by going to Best Buy. Best Buy has transistor radios for sale in both its retail locations as well as its online store.
What made radios portable in 1955?
The transistor!
What have taken the place of glass valves in radios?
transistor
Who popularized the transistor?
The general public. They wanted portable transistor radios, to listen to the radio anywhere.
Which 1947 invention made pocket-sized radios possible?
The transistor
Where one can find a vintage transistor radio?
One can find a vintage transistor radio on many websites online. Amazon sells these types of radios on their website. The price range for the radios go from $15.00-$250.00.
What year did transistor radios out?
The transistor was invented by Bell Labs in 1948. Applications in consumer devices followed within a few years after that.
What do you call the vacuum tubes used in transistor radios?
You don't, there aren't any. However some radios in the early 1950s did use both vacuum tubes and transistors. This was because early junction transistors were too slow to operate at RF so vacuum tubes were used in the RF and IF sections. These radios were called hybrid radios because they used both vacuum tubes and transistors.
What came after the transistor radio?
The scientists that were responsible for this invention was John Bardeen, Walter Brattain, and William Shockley. Bardeen, with a Ph.D. in mathematics and physics from Princeton University, was a specialist in the electron conducting properties of semiconductors.
What 1947 invention by Bell Telephone Laboratories spawned pocket sized radios?
It was the Transistor!
