Origin: Formed within English, by derivation. Etymons: auto- comb. form¹, -dyne suffix.

Etymology: < auto- comb. form¹ + -dyne suffix, after heterodyne adj.

Radio.

A. adj.

Designating or relating to a circuit in which the part used for detection (detection n. 3) is also used as the local oscillator; (also) designating radio reception which makes use of such a circuit.

1918 Circular U.S. Bureau of Standards No. 74. ii. 214 The electron tube may serve as a convenient source of local oscillations and at the same time as an amplifier and detector of the received signals. This is called the autodyne method.

1921 J. H. Morecroft Princ. Radio Communication vi. 483 In case the locally generated, high-frequency current is produced by the detecting tube itself, it is called autodyne reception.

1978 C. D. Ferris Introd. Bioinstrumentation v. 80 The capacitor forms part of the tuned circuit of either a Colpitts oscillator or autodyne detector.

2004 T. H. Lee Design CMOS Radio-frequency Integrated Circuits (ed. 2) xx. 769 In the autodyne circuit, the local oscillator is an echo of Armstrong's original regenerative circuit.

B. n.

An autodyne circuit. Now rare.

1930 U.S. Patent 1,748,277 2/2 These autodynes replace the heterodyne of Figure 1.

2003 I. V. Komarov & S. M. Smolskiy Fund. Short-range FM Radar ii. 16 The block diagram of this FM radar is given in Fig. 2.5. The main difference..is the use of an autodyne.
