Abstract This report describes the theory and implementation of a direct digital frequency synthesizer (DDS). This synthesizer will be used as a high resolution signal generator with an output frequency range of 25 Hz to 100 kHz, in 25 Hz steps. The report will provide a description of the realization of the DDS control system which enables the frequency synthesis, using a computer hardware description language to configure and implement the entire control system within a single programmable logic...

Abstract In the implementation of the wireless demodulator, numerous techniques exist to recover a carrier from the received signal. The selection of an appropriate recovery method depends on several conditions, among which are modulation type, acquisition time, tracking performance and the expected noise environment. This project first presents a discussion on the fundamental question of communications systems and includes sections on the transmitter, channel, and receiver. Receiver...
