Utilization of wireless technology for sound communication using TMS320 C6713

Abstract

The development of communication technology, both on algorithms and devices has been so rapid. The application of communication devices that previously used radio signal (wireless) would be more efficient if cable (on wire) is used instead. With a large number of buildings with wide locations, there are still many spaces that are not reachable by communication devices. Therefore, it is necessary to add a new communication tool that can be used to convey information in the campus environment intended for announcements, from one place to another or from one room to another simultaneously, both with point to multipoint as well as point to point characteristic which is suitable for internal communication and emergency situations. This wireless network can be expanded without using a cable backbone. In addition, with the equal sharing of access rights, the network will be more effective because it can be done anywhere as long as there is still a network connection. Audio effects can be applied in real time using DSP (Digital Signal Processing) Starter Kit TMS320C6713 by implementing in the equipment. In the audio input signal of 0.050 Vpp there is no change in the frequency of the original signal that is 1 Khz there is a change in the intensity of the sound produced 0.364 Vpp, 2 kHz to 0.280 Vpp while 3 kHz to 0.236 Vpp. There is a change in amplitude while the output frequency approaches the original signal frequency.
