Filter notch 50/60HZ -34DB
Notch active filter 50/60 Hz. A three positions switch allows function selection: 50Hz notch, 60Hz notch, no filter (band-pass for 5Hz-20KHz). Custom designed for ECG signal filtering for medical equipment, but, of course, it can be used for any other application in this frequency range.
* Input signal level: 10mVpp-10Vpp (it must be correlated with and lower than the DC supply); it can be negative because the filter has an internal circuit that generates negative DC.
* Stopband attenuation: 34dB
* DC power: 9V (but 6-14V ok)
* Connections: input - BNC; output - a 120cm coax white cable with BNC (there is a connector, maybe SMA, at the back, where the cable is plugged); a 30cm two wire black cable with connector for DC power (the white dashed line wire goes to +)
The output has a DC component, so the next stage should have a capacitor at the input.
