ExtractBiopsyFeature500

本代码包括小波包能量的提取，可以用于振动声发射噪声以及力信号的特征提取(this code is for energy of wpt Feature extraction such as Acoustic emission，vibration sound and force )

上电后,在BRAKE信号无效,且保护逻辑无输出的情况下? 电机按DIRECTION信号的方向转动? 电流传感放大器采样电机电枢电流,经13脚的RC网络转换为电压值,与D/A转换输出的预定阀值相比较。如果当前的电流使转换的电压值小于阀值?(Power after the BRAKE signal is invalid, and the protection logic no circumstances ? electrical output signals according to the direction of rotation DIRECTION ? current sensing amplifiers motor armature current sample by 13 feet of RC network is converted to voltage value, and D/A conversion output compared to the target threshold. If the current of current to voltage conversion value is less than threshold ?)
