Abstract
A device for double frequency transposition includes means for controlling the frequencies F, Fof a first and a second synthesizer, which are adapted to carry out the steps of (a) initializing the frequency Fat a first given value F; and (b) for a given pair of frequencies F, F, determining the frequency Fwith the aid of the following relations:ifand  (5),ifand  (6),ifand  (7),ifand  (8);and (c) if the value obtained for Flies in a frequency band of lower bound A·F−B·X and upper bound A·F+B·X, where A is a strictly positive integer and X is a given parameter, modifying the frequency Fto a second value Fdetermined so that the difference in absolute value between Fand Fsatisfies the following two conditions:|2|−2and (d) transmitting the frequency values Fand Fto said frequency synthesizers.
