#radio receiver
- Autodyne — A radio receiver circuit or electronic tube in which the same active element (vacuum tube or transistor) simultaneously fulfills the role of a local oscillator and a detector-mixer for high-frequency signals; a regenerative receiver adjusted to the brink of oscillation for receiving continuous waves.
- Autodyne — An electronic device or circuit (historically used in superheterodyne radio receivers) consisting of a single electron tube or transistor that simultaneously fulfills the roles of both a local oscillator and a mixer stage (frequency changer), converting the received signal frequency into a stable intermediate frequency.
