Drift Analysis of the Crosby Frequency-Modulated Transmitter Circuit

Component drift, sensitivity, and band-width expressions are combined in an over-all expression for frequency stability of the Crosby circuit. Using experimentally obtained constants in this expression, an equation is derived for drift in terms of frequency and frequency multiplication open to choice by the designer, and the results are shown as design curves. The equation is checked against actual conditions existing in a Crosby exciter unit.
