Abstract: A system for improving signal timing measurement resolution for an asynchronous measurement signal, the system being adapted to produce multiple phase shifted timing outputs, each having a fixed phase and being representative of timing information for the asynchronous measurement signal, and combine the multiple phase shifted timing outputs to provide a single combined timing output. Preferably but not essentially, the system is configured to produce the multiple phase shifted timing outputs using multiple fixed phase shifted clocks; multiple counters each one associated with one of the phase shifted clocks; and multiple samplers each one associated with one of the phase shifted clocks and its counter, wherein each clock, counter and sampler combination is used to sample the asynchronous measurement signal to produce a timing output, thereby to provide multiple phase shifted timing outputs.
