INSTALLATION WORKS to demonstrate features CLOSED LOOP SYNC

摘要

The invention relates to the means of study and can be used in the learning process to explore the features of operation of the phase locked loop system and a closed system synchronization in digital communications receivers.; The technical result is to increase the reliability of the information and visibility of the analysis depending on the amount and type of error messages by receiving a discrete quality functioning of the closed system when exposed synchronization additive noise on the signal.; The technical result is achieved in that the apparatus for demonstrating features of operating a closed synchronization system comprising a signal source, a source of interference, an adder, an amplitude limiter, a digital phase discriminator, comprising: a first differentiating element, a phase discriminator, a second differentiating unit and a controlled oscillator, decisive device multichannel display unit additionally introduced error logger. 1 Fig.
