The idea of using a super-regenerative radio to receive commercial FM stations can be found at various locations on the Internet. Because the circuit is so small, it might be impressive to lab ...

Circuits sometimes need a gain-of-one buffer to lower output impedance and prevent the load from interfering with the previous stage. For an application involving a 1.5-MHz, low-power transmitter and ...

In this lesson, students build two circuits and explore how transistors function. When Bell Labs introduced the transistor in June of 1948, a spokesman proudly announced "This cylindrical object . . .
