| Abstract: | Using piezoelectric sensors and low-noise low-power amplifier, a probe for leak location is designed. With A/D-D/A converter TLV320AIC10s and one DSP chip TMS320C5402 which receives the sampled data through McBSPO,the hardwired connection of the two-way real-time sampling and analyzing system for audio signals is accomplished. The software program of the system is completed by using assembly language in conjunction with C code. The experiment results indicate that the system is reliable and practical. |
