Abstract
For testing a frequency divider, oscillations are produced and wave-shaped into a series of dock pulses. The dock pulses are supplied to a frequency divider under test. A window pulse of duration equal to one cycle of the output pulses of the frequency divider is used to sample the clock pulses. The sampled clock pulses are counted and compared with a reference value. Depending on the number of the sampled clock pulses relative to the reference value, an output voltage at one of two discrete values is produced to indicate the result of the test.
