An nth-root extracting device, most useful as a square-root extractor, which accepts an input signal and derives therefrom an output signal which is proportional to the root of the input signal. The input signal goes to one input terminal of a summer circuit, the output signal from which passes through an integrating device and then through a feedback loop to another input terminal of the summer. The feedback loop raises the output signal of the integrator to the nth power so that the output signal of the integrator is the nth root of the input signal.
