<p>1508185 Clock-pulse generator PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 22 May 1975 [24 June 1974] 22211/75 Heading H3T Inverse clock-pulse trains V0P, V1P, Fig. 3, of alternatively positive and negative going floating pulses, are produced by switching a constant current source CS, Fig. 2, connected across a delay line D, on and off, i, Fig. 3. The pulses are distributed to various remote points by appropriate decoupling transformers (Fig. 4, not shown) in such a way that the delay line is terminated by its characteristic impedance ZB.</p> |
