This page three adjustable notch filters configurations are shown . They can be used in your small pre-amp or amplifier project to filter out any HUM at 50 Hz ( European ) or 60Hz . By substituting the capacitors values in the bridge other frequencies can be used . All op-amps configuration requires a +/- […]
