摘要：

Detecting acoustic emission signals are very important for analysis. In this paper we have proposed a hardware based portable, energy efficient and accurate acoustic emission signal acquisition system based on DSP processor, design of acoustic piezoelectric sensor and a signal conditioning unit with variable gain amplifier and wide band pass filter. Different signal conditioning unit design consideration and wavelet based signal denoising procedure is also discussed in this work. This work would be useful for hardware based signal acquisition system design.
