Abstract

1,036,563. Pulse modulation systems. BODENSEEWERK PERKIN-ELMER & CO. G.m.b.H. May 30, 1963 [June 5, 19621, No. 21721/63. Heading H4L. [Also in Division G4] A voltage to frequency converter comprises a Miller integrator 10 in which the integrator feedback capacitor 11 is shunted by means (e.g. a glow tube 18) to discharge it to one level when the charge on it reaches another level, thus producing an output signal having a frequency proportional to the input voltage.
