An adaptive measurement system measures a transition rate associated with an output of a device. An input signal that is characteristic of the output of the device is received by an input signal-to-frequency converter, which changes state based upon a characteristic of the input signal. The input signal-to-frequency converter provides a second signal, which reflects the state changes of the input signal-to-frequency converter. The second signal is sampled over a sample period and an instance of average transition rate is determined. A control subsystem may use the instance of average transition rate for regulating the device.
