Low-Power Analog Processing for Sensing Applications: Low-Frequency Harmonic Signal Classification
A low-power analog sensor front-end is described that reduces the energy required to extract environmental sensing spectral features without using Fast Fouri´er Transform (FFT) or wavelet transforms. An Analog Harmonic Transform (AHT) allows selection of only the features needed by the back-end, in...
