Digital Audio Wireless Transmission System Theoretical Analysis And Hardware Implementation

The subject棓Digital Audio Wireless System?is discussed in this paper. According to the request of the subject, the system was designed, a set of prototype was accomplished and the transmitting the analog audio signal within digital wireless mode was realized. The following list is the author抯 work: (1) According to the require of the subject, designed the construction of the system. (2) Analyzed the function parts of the system. And discussed the AZ Modulation, channel multiplexldemultiplex and digital frequency modulation in the discourse. (3) Made familiar with the ICs, which were chosen, and complete the design of the PCB. Basing on them, the work of transmitting the analog audio signal within digital wireless mode was accomplished. (4) The parameters of the system were tested and the advices of improving the system were given following.
