Abstract
A speed limit system providing a passing of a given limit is disclosed. The speed-limit indicator comprises a frequency-voltage converter receiving at its input a signal which is produced by a sensor indicative of vehicle speed. A detection circuit comprising a frequency-voltage converter and a comparator followed by a gate circuit and signaling means are provided. The comparator utilizes the output of the voltage from the converter and a reference voltage which represents the speed limit. The gate circuit is interposed between the output of the comparator and the signaling means. A control signal is provided to the gate circuit, and in accordance with the state of that control signal, the gate circuit transmits or blocks the output signal of the comparator to the signaling means.
