This invention discloses a device for converting the rate of a pulse train which is proportional to the velocity of a vehicle wheel into a binary number for use in a digital computer for anti-skid control systems wherein the pulse train is supplied to a comparator, the output of the comparator being coupled to the input of a storage register which cumulatively adds to its contents, taking due consideration of the sign of the input. A frequency generator which is controlled by the contents of the storage register, with the comparison pulse train produced by the generator being supplied to the comparator and an adapter being added to establish a difference between the frequencies of the two pulse trains in the form of a binary number, which binary number is supplied to said register so that the content of said register represents the binary number corresponding to the frequency. The comparator and the register are both controlled by a clock pulse generator. |
