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.
