Abstract
An improved modulator for an anti-skid brake control system generates a modulated brake control signal as a time integral function of the difference between an input signal indicative of a braking condition and a variable threshold signal. The preferred embodiment includes a computer which stores a number of threshold signals. An appropriate one of these threshold signals is selected depending on the magnitude of the velocity of the braked wheel.
