This work studies the effects of the prefilter bandwidth on the carrier wave phase synchronizers. We consider three different prefilter bandwidths namely B1= ∞(infinite), B2=2.tx and B3=1.tx, where tx is the transmission rate. We consider also four carrier wave phase synchronizers, namely, the analog (ana), the hybrid (hib), the combinational (cmb), and the sequential (seq). The objective is to study...
This work studies the effects of the prefilter bandwidth in the symbol synchronizers of mixed loop. The prefilter bandwidth B is switched between three values, first B1=∞ (infinite), after B2=2.tx and next B3=1.tx, where tx is the bit rate. The synchronizer of mixed loop is based on a tuned filter followed of a PLL (Phase Lock Loop). We consider four PLL types, namely, the analog (ana), hybrid (hib),...
This work studies the effects of the prefilter bandwidth on the symbol synchronizers of closed loop. The prefilter changes its bandwidth B, first B1=∞ (infinite), after B2=2.tx and next B3=1.tx, tx is the bit rate. The symbol synchronizer is based on a closed loop blocks. We consider four types, namely, the analog (ana), hybrid (hib), combinational (cmb) and sequential (seq). The objective is to study...
This work studies the effects of the prefilter bandwidth on the open loop symbol synchronizers. We consider three different prefilter bandwidth, namely, B1=∞ (infinite), B2=2.tx and B3=1.tx, where tx is the transmission rate. We consider also four open loop symbol synchronizers, namely, the tank (tank), the SAW (SAW), the monostable (mon), and the astable (ast). The objective is to study the prefilter...
This work presents the synchronizer based on pulse comparation, between variable and fixed pulses. This synchronizer has two variants, one operating by both transitions at the bit rate and other operating by positive transitions at half rate. Each variant has two versions namely the manual and the automatic. The objective is to study the four synchronizers and evaluate their output jitter UIRMS (Unit...
This work studies the effects of the prefilter bandwidth in the sequential symbol synchronizers based on clock sampling by positive transitions. The prefilter bandwidth B is switched between three values, namely B1=∞, B2=2. tx and B3=1. tx, where tx is the bit rate. The synchronizer has two variants, one discrete and other continuous. Each variant has two versions, one manual and other automatic....
