Abstract

Procedure to generate the pilot frequency supergrupo of 411.92 khz. The frequency of 12khz from the master oscillator goes to a frequency bender (1), where 24 khz is obtained; in a square wave generator (2) and in the lc filter (3) the frequency of 24 khz is quadricated and filtered respectively, to select the frequency of 168 khz; this frequency goes to a frequency divider (5) and to an lc filter (6), obtaining the 1.68 khz signal, which is used as an attack signal to a modulator (7); the output signal of such modulator goes to an lc filter (8), so that a signal of 21.68 khz is obtained, signal that in some time goes to a square wave generator (9) and a filter (10) to obtain the desired 411.92 khz.
