Noun
squegger (plural squeggers)
(electronics) An irregular oscillator, one exhibiting squegging.
By timing the squegger so that the dot arrived at the far end of the display at the same time as expected signals reflected off the Heaviside layer, the altitude of the layer could be determined. Source: Internet
To determine the altitude of the layer, Watt, Appleton and others developed the ' squegger ' to develop a ' time base ' display, which would cause the oscilloscope's dot to move smoothly across the display at very high speed. Source: Internet
