A method can be used for monitoring a processing circuit. The processing circuit generates a response to a request and the response is compared with an expected response. A pass pulse is generated when the response matches the expected response. The causing, comparing and generating steps are repeated a number of times A frequency at which pass pulses occur is evaluated.

In accordance with an embodiment, a method for operating a signal converter includes converting an analog input signal to a digital output signal, comprising by comparing the analog input signal to an analog comparison signal, and detecting whether the analog input signal exceeds a predetermined maximum or minimum threshold by comparing the analog input signal to an analog threshold signal. The analog comparison signal and the analog threshold signal are generated by a same digital-to-analog converter.
