Abstract :
The following phenomena are discussed in relation to experimental observations on a number of frequency division schemes: "division" of a wave containing several frequencies; phase ambiguity; and strobing. Phase ambiguity is believed to be a fundamental limitation, and the results of a number of previous experiments are attributed to its effects.
