Abstract

Disclosed is a logarithmic detector comprising: an amplifier element; means for setting a frequency of operation of the detector; and a controller, wherein an input signal to the amplifier element is arranged to cause an oscillation in the amplifier element, and the controller is operable to sense a pre-determined threshold, indicative of oscillation and, in response to sensing said threshold, to interrupt the oscillation of the amplifier such that the frequency of said interruption is proportional to the logarithm of the power of the input signal.
