Abstract
An electrical circuit for conditioning an analog electrical input signal into an analog electrical output signal includes a threshold circuit. The threshold circuit is configured to set a value of a conditioning parameter, under control of the analog electrical input signal and based on an electrical threshold. The threshold circuit is configured to set the conditioning parameter to, in response to the analog electrical input signal being below the electrical threshold, a first value. The threshold circuit is configured to set the conditioning parameter to, in response to the analog electrical input signal exceeding the electrical threshold, a second value different from the first value.
