A simple AM transistor radio can be made with surprisingly few components, but for a circuit with a reasonable performance they suggest six transistors to be the optimal number. If we think about ...

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 ...

The mosfet is off if the input voltage is normally less than \(2.0 V\). By looking at a circuit diagram of a transistor switching circuit, you should be able to say what the circuit is used for ...
