Etymology
Etymology Information

'autodyne' is formed from the Greek prefix 'auto-' meaning 'self' and the element '-dyne' (from Greek 'dunamis' meaning 'power' or 'force'), coined in English in the early 20th century in technical contexts.

Historical Evolution

'autodyne' was coined in English as a compound (modeled on terms like 'heterodyne') and came into use in radio-engineering writings in the early 1900s to describe circuits where oscillation and detection occur in the same device.

Meaning Changes

Originally built from roots meaning 'self' + 'power/force', the term evolved to refer specifically to a self-oscillating or self-mixing type of radio circuit or receiver rather than a literal 'self-force'.

Meanings by Part of Speech

Noun 1

a type of radio receiver or circuit in which the detector device also functions as the local oscillator or regenerative element (i.e., a receiver that uses self-oscillation or mixing within a single device).

The technician adjusted the autodyne to reduce interference and improve sensitivity.
