Abstract

In this paper we present four types of normal symbol synchronizers, namely the analog, the hybrid, the combinational and the sequential.
The synchronous sequential synchronizer has capacities that permits to obtain the correspondent asynchronous version.
So the fiip flop is substituted by logic with feedback. Then all the synchronizers use only logic gates.
The main objective is to develop the synchronous sequential synchronizer and then to study and compare the performance of the two versions.
