1. A radio receiver or oscillator that uses a single vacuum tube or transistor to generate both the local oscillation and amplification needed for reception or frequency conversion.
Usage: electronics; radio technology; technical

1. Of or relating to a radio circuit or receiver that employs the autodyne principle.
Usage: electronics; technical

Examples

• The autodyne receiver was an early innovation that reduced the number of tubes required in radio sets.
• Engineers designed an autodyne circuit to simplify the heterodyne conversion process.
• Early crystal radio enthusiasts experimented with autodyne configurations to improve sensitivity.
• The autodyne principle allowed manufacturers to produce more compact and affordable radio receivers.
• Modern semiconductor autodyne circuits are still used in some specialized applications.
