{vibrate}, {vacillate}, {oscillate}]
2: move or swing from side to side regularly; "the needle on the
meter was oscillating" [synonym: {oscillate}, {vibrate}]

Oscillate \Os"cil*late\ ([o^]s"s[i^]l*l[=a]t), v. i. [imp. & p.
p. {Oscillated} ([o^]s"s[i^]l*l[=a]`t[e^]d); p. pr. & vb. n.
{Oscillating} ([o^]s"s[i^]l*l[=a]`t[i^]ng).] [L. oscillare to
swing, fr. oscillum a swing, a little mask or puppet made to
be hung from trees and swing in the wind, prob. orig., a
little mouth, a dim. from os mouth. See {Oral}, and cf.

in a fickle or fluctuating manner; to change repeatedly,

  • Why does this current limiter oscillate? | Forum for Electronics
    I'm struggling to figure out why the circuit below oscillate at about 2-300khz Changing the value of C10 seems to have no effect, neither does adding an output gate resistor, or adding a input resistor to the non-inverting input The amplitude of the oscillations goes down if I add a resistor
  • LC VCO doesnt oscillate in transient analysis
    Can anyone comment on how to get the LC VCO to oscillate in transient analysis please? Initial conditions are set, and PSS Pnoise works fine But in transient analysis VCO simply doesn't oscillate Thank you
  • Oscillators using Op. Amp. How they start to oscillate
    Hello This is my first topic in this forum I wonder if someone can help me with a question I have from some time ago When studying about oscillators using Op Amp , they always teach you about how to calculate the value of resistors, capacitors, and other external elements, to get a

    Hello everyone, I’m working on designing a 12 GHz Colpitts oscillator using a BFP720 transistor in a common-emitter configuration I’ve spent the last two months trying various topologies and bias networks, but I’m still encountering issues I’d really appreciate if someone with experience in
  • [SOLVED] - PIC18F47J53 Crystal does not oscillate
    Hello, Refering to PIC18F47J53 datasheet it can be clocked up to 48MHz, but I can't make it to work with such frequency crystal I'll explain everything from the begining: I set oscillator to be in HS mode and CPU clock division to be 1:1 So, the CPU clock should be 48MHz (with 48MHz crystal)
