### Advantages of synchronous data communications

#### Superior noise immunity due to matched filtering; that is. the symbol or bit is averaged over its entire duration giving optimum noise and interference rejection and maximizing signal power. #### Can accommodate higher data rates than asynchronous systems.

### Disadvantages of synchronous data communications

#### Requires finite time for synchronization to occur. #### Is more expensive and complex than asynchronous operation. #### Cannot easily accommodate variable symbol rates.
