Abstract
1,273,975. Square wave generator circuits. GENERAL ELECTRIC CO. Ltd. 1 Aug., 1969 [8 May, 1968], No. 21789/68. Heading H3T. A square wave generator of the type in which transitions between zero and one states are circulated through a delay line in response to the level at two tappings, N, P, on the line, the recirculation is controlled by the level on a group of tappings so as to prevent operation at multiples of the required repetition rate. Thus only the presence of a "one" signal at all tapping points A to H covering at least a third of the line and a "one" at N+P allows the recirculation of a zero through gate 3. The useful output is controlled by two tappings R, S on the line the latter tapping controlling the turn on of the gate and the former tapping the turn off to allow for the unequal turn on and turn off speeds and so equalize the two halves of the output wave.
