This work studies the prefilter bandwidth effects in four asynchronous sequential symbol synchronizers. We consider three prefilter bandwidths namely B1=∞ ∞ ∞ ∞, B2=2.tx and B3=1.tx, where tx is the bit rate. The synchronizer has two variants one asynchronous by both transitions at bit rate and other asynchronous by both transitions at half bit rate. Each variant has two versions namely the manual and automatic. The objective is to study the prefilter with the four synchronizers and to evaluate
