Abstract:

The patent relates to an oscillator which provides an f sub 1V sub 1 analog signal to a summing amplifier. The same oscillator signal is conducted through a frequency multiplier and voltage attenuator to produce an f sub 2V sub 2 signal also applied to the summing amplifier. The amplifier output is converted to digital signal samples by the analog to digital AD converter to be tested and a computer counts the number of f sub 2 samples in an f sub 1 sample. By comparing received f sub 2 samples with the expected f sub 2 samples, resolution is determined.
