Description in English
The sampled and higher order systems are discussed and means for stability checking, with the computer simulation of the Bode plots, are mentioned. It is shown that computer plotting of the PLL transfer function H(s) and 1-H(s), with the assistance of the open loop gain G(s), provides many information influence about noise of different noise sources; i.e., noise of the reference oscillator, of the voltage controlled oscillator, of the phase detector and of inevitable filters.
