1. An emissions-suppression circuit comprising:
a notch filter associated with a frequency range, the notch filter including a first end and a second end;
a first switch configured to, in a filter state, couple an input node to the first end of the notch filter and configured to, in a bypass state, couple the input node to an output node and bypass a second switch; and
the second switch disposed between the second end of the notch filter and the output node, the second switch is a single-pole-single-throw switch configured to selectively activate, the second switch configured to activate in the filter state.
