Abstract
In an input control unit for a vehicle anti-skid braking system, a wheel-speed sensor delivers speed signals to the first input of a differential amplifier. Simultaneously, a capacitor is charged through a resistor and a diode. The capacitor is discharged at a constant rate into a device connected to the second input of the differential amplifier. Another diode prevents the voltage across the capacitor from becoming higher than the voltage of the speed signals. The braking pressure is released for the duration of output signals produced by the differential amplifier. The duration of these signals is kept within safe limits due to the fact that the additional diode limits the voltage across the capacitor.
