The invention pertains to a system for determining the time between the receipt of two different signals, includes a voltage ramp generator which generates a time dependent voltage signal upon receipt of a timing pulse at a time T1, and provides the instantaneous value of the voltage signal when the voltage ramp generator receives an input signal having a predetermined threshold value at time T2. A data processor coupled to receive the voltage signal, generates the timing pulse, and determines a time difference delta T from the voltage signal, where ATT2-T1.
