1. An apparatus comprising:
an impulse generation circuit for applying an impulse to a resonant circuit comprising an inductive element configured to inductively heat a susceptor and a capacitor, wherein the applied impulse induces an impulse response between the capacitor and the inductive element of the resonant circuit, wherein the impulse response has a resonant frequency; and
an output circuit configured to provide an output signal dependent on one or more properties of the impulse response, wherein the output circuit comprises an edge detection circuit for identifying edges of said impulse response.
