Sound Monitoring System

Members : Qinglie Zhu, Zheng Zhao, Junhao Zhu, Zhiyuan Zhang Advisor: Valerio Selis General Ideas: In this week, the group succeeded in constructing the entire circuit consisting of amplifier circuit and ADC circuit. Furthermore, the algorithm of the sound monitoring system has been optimized as well. Next, in order to protect the circuit from damaging, the circuit was packaged. Finally, the design of poster is finished in this week. Experience of the Experiment: 1.     Reconstruct the sound monitoring system For the purpose of stability and beauty, the circuit was reconstructed in the lab. Differentiating from the previous circuit, the length of wires and pins were cut so that the components can be fixed in the breadboard. The entire circuit is shown as Figure 1 below.  Figure 1. The Entire Circuit 2.     The Optimization of Algorithm As for the algorithm part, the original one was optimized in this week. In detailed, the first part that needed to be
