Abstract:

Synthesizer is an electronic system that a range of frequencies to produce a reference frequency. In terms of frequency synthesizers are three types. The first technique, PLL Synthesizer of various blocks including phase detector, loop filter, voltage controlled oscillator (VCO), and a split ring and a divide loop on the path Feedback it was made. The two technique, the direct analog synthesis(DAS) is known as the very first approach for frequency generation. This technique used to stage of frequency multipliers, mixers, dividers and filters. DAS to implement PLL has a more complex and thus more expensive. The third technique, is direct digital synthesis (DDS), which is a digital signal processing (DSP) discipline and uses digital circuitry and techniques to create, manipulate, and modulate a signal, digitally, and eventually convert the digital signal to its analog form by using a digital - to - analog converter (DAC).
