Abstract

1526256 CRT displays ELECTROACUSTIC GmbH 20 Oct 1975 [8 Nov 1974] 43036/75 Heading H4T [Also in Division G1] In an echo-sounding system, echo signals are displayed on a cathode ray tube as horizontal deflections from a vertical time axis by horizontally deflecting the electron beam, darkened, by a cyclically varying current and brightening the electron beam when and for as long as a voltage proportional to the instantaneous value of the deflection current does not exceed a voltage derived from the echo signal. To mark both sides of the time axis, two comparators 1, 2 compare the echo signal, erect 3 and inverted 5, with the deflection signal.
