transistor oscillator การใช้

Johnson described three ways of producing an integrated one-transistor oscillator.
Original sets used a transistor oscillator; newer phones use an integrated circuit.
On September 12, he presented the first IC prototype, which was a single-transistor oscillator with a distributed RC feedback, repeating the idea and the circuit in the 1953 patent by Johnson.
IMD is also distinct from intentional modulation ( such as a frequency mixer in superheterodyne receivers ) where signals to be modulated are presented to an intentional nonlinear element ( mixers such as mixer diodes and even single-transistor oscillator-mixer circuits.
The Accutron " ( right ) ", an electromechanical watch developed by Max Hetzel and manufactured by Bulova beginning in 1960, used a 360-hertz steel tuning fork as its timekeeper, powered by electromagnets attached to a battery-powered transistor oscillator circuit.
