Abstract

See full text

Process for adjusting a time base by inhibiting clock pulses supplied by a clock circuit, this adjustment process comprising the following steps:

    selecting an inhibition period;determining a first number N of clock pulses to be suppressed per inhibition period to adjust over each inhibition period the number of clock pulses activating a frequency divider circuit such that the frequency of the time base comes closest to a reference unit frequency;selecting a plurality K of sub-periods for each inhibition period;suppressing in each sub-period a second number N1 of clock pulses corresponding to the result of the integral division of the first number by the number of sub-periods, andin addition to the suppression of the preceding step, suppressing in each inhibition period a third number N2 of clock pulses corresponding to the remainder of said integral division.
