Abstract

978, 269. Electric selective signalling systems. R.& R. RESEARCH Ltd. March 5,1963 [March 5,1962], No. 8399/62. Heading G4H. A time varying voltage 2, Fig. 1, is integrated by frequency modulating an oscillator 1 in accordance with the voltage, mixing 4 the result with a reference local oscillator 3, and by shaping 5, 6 and counting 7 the cycles of the difference frequency.
