It is shown that the distortion generated in fm systems by small sinusoidal ripples on either group delay or amplitude characteristics can be evaluated in terms of the distortion due to a single echo. Using results already established for echo distortion, curves are plotted relating intermodulation distortion of a frequency-division-multiplex signal to the amplitude, periodicity, and location of the small sinusoidal ripple for a 600 channel system. These curves are of value in estimating permissible limits of variation of transmission characteristics over the significant rf band.
