They had to catch the attention of the public. That happened with the hand-held radio. The first transistor radio was a joint project between the Regency Division of Industrial Development ...

A handheld AM or FM radio. All handheld radios, as well as desktop radios, use transistors, both discrete as well as contained in chips. The transistor radio was one of the first consumer devices ...

The humble transistor radio is one of those consumer devices that stubbornly refuses to go away, but it’s fair to say that it’s not the mover and shaker in the world of electronics it might on ...

Western Electric did not want to share its crystal-growing technology, so in 1954, the team created an alloy transistor. However, it failed to work well at radio frequencies, so they shifted to ...

This germanium had an excess of electrons, but when an electric signal traveled ... Of course, a transistor in a telephone or in a radio has to handle complex signals. The output contact can ...

Before the MP3 was the Walkman and before that was the "tranny" - the transistor radio. Personal radios existed before their mass popularity in the 1960's, but then they became a teenage 'must-have'.

The transistor is on, when the input voltage is greater than or equal to \(0.7 V\). The transistor is off if the input voltage is less than \(0.7 V\). The mosfet is on, when the input voltage is ...
