In electronics, a differentiator is a circuit that outputs a signal approximately proportional to the rate of change (i.e. the derivative with respect to time) of its input signal. Because the derivative of a sinusoid is another sinusoid whose amplitude is multiplied by its frequency, a true differentiator that works across all frequencies can't be realized (as its gain would have to increase indefinitely as frequency increase). Real circuits such as a 1-order high-pass filter are able to approximate differentiation at lower frequencies by limiting the gain above its cutoff frequency. An activ
In elettronica il derivatore analogico è un importante utilizzo dell'amplificatore operazionale. Prima dell'avvento dell'elettronica digitale l'utilizzo degli amplificatori operazionali era notevole per ottenere operazioni matematiche tramite segnali, come la derivazione e l'integrazione.
