Abstract: Dynamic lung sound signal analysis and processing require synchronous multi-channel data acquisition system. In noninvasive and no pain lung sound diagnosis system, the highly accurate, synchronous and stable data acquisition system is the foundation of fellow-up work. In order to acquire the array data of lung sound, higher speed, reliability and synchronous data acquisition system can meet the requests. Lung sound signal was produced by lung vibration during air exchange. Simultaneous sampling maintains the phase information and provides us w...
