  • Abstract
    An electronic differentiator specifically for low-frequency signals is described. The difference between a signal and its staircase approximation is computed; the peaks of this function approximate the time derivative of the input signal. By regulating the width of the steps in the staircase function, very slow signals can be differentiated.
