Considering the situation of the low--frequency electronic equipment which is generally affected by the 50Hz power frequency interference, based on the thorough study of filter circuits, a tunable Q value double T active filter circuits which can effectively filter out 50 Hz frequency and its second harmonic is made and designed with the help of circuit simulated tools. The circuit has excellent filtering, amplification, feedback, and regulation function, which can be widely applied in the fields of low frequency signal and information process, data transmission, and interference suppression.
