Abstract: As one example, a filter apparatus includes an input to receive an electrical input signal. The filter apparatus includes a forward path connected between the input and an output of the filter apparatus. A feedback path is connected to provide feedback to the forward path based on an output signal at the output of the filter apparatus. A filter bypass is configured to provide the input signal directly to the output and to the feedback path for an activation phase of the filter apparatus. Diagnostics may also be performed.
