چکیده
Digital tuning systems are fast replacing the conventional mechanical systems in AM/FM and television receivers. The desirability of the digital approach is mainly due to the following features: Y Precise tuning of station frequencies Y Exact digital frequency display Y Keyboard entry of desired frequency Y Virtually unlimited station memory Y Up/down scanning through the band Y Station ‘‘search’’ (stop on next active station) Y Power on to the last station Y Easy option for time-of-day clock

Comparative Study of PLL, DDS and DDS-based PLL Synthesis Techniques for Communication System
The phase locked loop(PLL) has been widely used in wireless communication systems due to the high frequency resolution and the short locking time. The Direct Digital Synthesis(DDS) is also an emerging and maturing signal generation technology. But another advanced technique in which, DDS signal is mixed with the voltage-control oscillator output in the PLL feedback path. This solution helps in ...

متن کاملAll Digital Ultra-Fast Acquisition PLL
Frequency synthesizers find use in all high frequency applications such as communications, radar, digital communications, electronic imaging and spectroscopy [1]. There are three main techniques commonly used 1) PLL synthesizers based on a feedback mechanism to lock to a reference frequency. The popularity of the PLL is due to their extended tracking range and low cost. 2) Direct analog frequen...
