Frequency synthesis device and method

摘要

A frequency synthesis device including: a first generator configured to generate a periodic signal of frequency f1; a second and third generator, coupled with the first generator and configured to receive as an input the periodic signal of frequency f1 and to generate a signal SG corresponding to a train of oscillations of frequency substantially equal to N·f1, of a time less than T1=1/f1 and repeated periodically at the frequency f1, where N is a whole number greater than 1; and a fourth generator configured to generate, from the signal SG, a periodic signal wherein a frequency spectrum includes a primary line of frequency f2=(N+i)·f1, where i is a whole number.

1. A frequency synthesis device, comprising:
a first generator configured to generate a periodic signal of frequency fl; a second generator, coupled with the first generator and configured to receive as an input the periodic signal of frequency f1 and generate a signal SG corresponding to a train of oscillations of frequency substantially equal to N·f1, of a time less than T1 =/f1 and repeated periodically at the frequency f1 , where N is a whole number greater than 1; a third generator configured to generate, from the signal SG, a periodic signal of frequency f2 by acting as a band-pass filter applied to the signal SG and rejecting from a frequency spectrum of the periodic signal of frequency f2 lines other than a primary line of the periodic signal of frequency f2, wherein said frequency spectrum comprises the primary line of frequency f2=(N+i)·fl, where i is a whole number.
