TheMatlab Signal Processing Toolboxprovides the commandspectrogramfor computing and displaying a spectrogram (and Octave has the commandstft). As a side effect, it returns the complex STFT data in amatrix. Themyspectrogramfunction below illustrates computation of a spectrogram in matlab for purposes o...

findpeaks是Signal Processing Toolbox的一项功能,用于查找加速度幅值数据的局部最大值。仅将最小高度超过一个标准偏差的峰视为台阶。该阈值应通过实验进行调整,以匹配人在行走时的运动水平,地板的硬度等。 minPeakHeight = std(accelScalarNoG);%标准差 [pks,locs] = findpeaks(accelScalarNoG,'MINPEAKHEIGHT',min...
In the examples below, we used a PicoScope 5244B oscilloscope. Comparing data captures using 8-bit and 16-bit resolution In this example, we compare and contrast data acquisition of the same signal source first with the PicoScope set to 8-bit resolution, then to 16-bit resoluti...
