<p>A solution of universal clock system enables universal construction of the clock system and producing clock pulses with fixed and also variable repetition period, which is a result of program control of microprocessor. Setting pulses of particular subsystems are derived from pulses of basic oscillator (1) by reason of precise definition their time sequence. Because of that reason, a divider (3) and a microprocessor (4) is used, which produce gate pulses upon the control voltage on input terminal (11) of microprocessor (4) from control circuit (2). The gate pulses go to output terminal (13) of the microprocessor. The microprocessor (4) arranged the transition those pulses coming to input terminal (12) of clock pulses of selector only at intervals given by variable repetition period produced by the microprocessor (4). Thereby the high stability of the clock pulses (16) is secured.</p> |
