self-osciˈllation Electronics.
[self- 3 b.]
The generation of continuous oscillations in a circuit, amplifier, etc., in circumstances of excessive positive feedback.
1921J. Scott-Taggart Thermionic Tubes vi. 204 The potentiometer..if suitably adjusted, will effectually prevent self-oscillation. 1943K. R. Sturley Radio Receiver Design i. viii. 394 As the coupling between anode circuit and input is increased a point is reached where self-oscillation occurs. 1963B. Fozard Instrumentation Nuclear Reactors x. 118 Feedback may be defined as positive, in which case it produces an increase in gain and may lead to instability and self-oscillation.
Hence [as back-formation] self-ˈoscillate v. intr., to display self-oscillation; self-ˈoscillating ppl. a.
1928L. S. Palmer Wireless Princ. & Pract. ix. 328 Similar trouble arises when unstable receiving circuits self-oscillate accidentally. 1962Simpson & Richards Physical Princ. Junction Transistors xviii. 459 Such a circuit..is called a self-oscillating mixer or a frequency converter stage. |
