Abstract :
The convergence behaviour of the first-order multisampling digital tanlock loop (MSDTL) with phase and frequency step inputs is investigated. The MSDTL yields extended locking range, and reduced steady-state mean and variance of phase error as compared with a conventional DTL. It is shown that as the number of samples taken in one period of the received signal increases, the convergence time of the first-order MSDTL decreases sharply.
