Definition of reflection oscillator in English:

reflection oscillator


  • 1A valve oscillator having two closely-spaced grids with an alternating electric field between them, through which electrons pass twice, once in each direction.

  • 2An oscillator consisting of a resonator (a tuned circuit) and an active device such as a transistor connected in such a way that instability in the latter causes oscillations to build up in the former until stability is reached.
