Abstract :
A formal series expansion is given for the powerdensity spectrum of a carrier frequency-modulated by a random signal. The first term of the series is the well-known Woodward term usually obtained heuristically by considering the FM wave as a slowly changing sinusoid. Higher order terms represent corrections to this quasi-static description.
