  • Abstract
    A frequency modulator is realised using a gyrator one of whose gyration conductànces is varied with the audio signal. The gyrator, together with two capacitors, forms the tank circuit of a negative impedance convertor oscillator. A linear peak frequency deviation exceeding ±2.5% was obtained, the s.n.r. being 64 dB.
