Abstract

874,691. Pulse modulation circuits. LANDIS & GYR A.G. Aug. 18, 1959 [Aug. 20, 1958], No. 28197/59. Class 40(5) The repetition frequency of a pulse train generated by a multivibrator T 1 , T 2 , is made linearly proportional to a D.C. control voltage Us by including a parallel resistance-capacitance network R 2 , C 2 in the input circuit of the multivibrator.
