The transverse bunchbybunch feedback system has been constructed at Hefei light source to cure and damp the coupled bunch instability. There are two important modules in the system: the vector calculation module and the notch filter. The vector calculation module is a signal processing module used to adjust the phase of the feedback signals and the notch filter can filter the revolution frequency component in a signal, which will save the feedback power.
