1. An electric circuit for filtering glitches, the electric circuit comprising:
a filter;
an inverter circuit electrically coupled to an output of the filter; and
a reset circuit electrically coupled to the output of the filter, wherein the reset circuit is arranged to:
pull the output of the filter high when an input signal to the electric circuit and the output of the inverter circuit are both low;
pull the output of the filter low when the input signal to the electric circuit and the output of the inverter circuit are both high; and
pass the output of the filter when (i) the input signal to the electric circuit is high and the output of the inverter circuit is low or (ii) the input signal to the electric circuit is low and the output of the inverter circuit is high.
