In order to cure the transverse coupled bunch instabilities due to higher order modes of RF cavities and resistive wall impedance in the BEPCII storage ring, an analog bunch-by-bunch feedback system was designed and used. The main components are two sets of beam oscillation detectors, betatron phase adjuster, notch filter and stripline kicker. This paper will describe system parameters, specifications of key components and experiment results.
