The paper aims at the thyristor power supply device witha synchronous circuit of phase locked loop and frequency multiplier .

The paper introduced hardware design,principle of phase sequence measurement and software realization of synchronous circuit of an intelligent soft starter taking INTEL 80C196MC as control chip.

The experiment indicates that this circuit using synchronization circuit design can generate a stable and reliable driving waveform.

Comparison of impact to the performance of synchronization circuits made by zero and non zero clock skew scheduling is given, and methods of improving the performance of circuits through modulating clock skew are analyzed to show how non zero clock skew scheduling can improve the performance of circuits.

This paper presents a kind of synchronization circuits for digital communication system and analyses the theory of the whole circuit.

This paper investigates the structure and algorithms of Ad Hoc wireless network based on UWB and circuit switching technologies.

This paper explores a new method--Integration of Circuit Switching and Packet Switching based on TCP Switching.

The concept of IP telecomm network is analyzed from history view first, the main difference between packet switching and circuit switching is then put out, which indicates the unique merit of the circuit switching.
