The patent describes a serrodyne generator providing a constant peak amplitude sawtooth signal wherein a voltage controlled multivibrator VCM determines the frequency at which a capacitor is discharged with the VCM frequency being varied by a common sweep signal. In order to maintain a constant amplitude, the current source for the capacitor is swept at the same rate as the VCM by the common sweep signal. The serrodyne generator is used for electronic countermeasures applications.
