Abstract
This paper describes an electronically frequency-modulated oscillator of the resistance-capacitance type which has been developed to facilitate rapid and accurate calibration and testing of flutter-measuring equipment; specifically, of the portable flutter indicator used in theater service work. It supersedes mechanically driven capacitor devices for producing the frequency-modulated 3000-cycle signal used for flutter-indicator calibration. It possesses the advantages of better frequency stability, purer wave form, and absence of spurious output impulses.
