摘要： A hysteresis limiter including a hysteresis limiting circuit, a signal variance tracking device and a reference voltage selecting device can dynamically track variance of signals and adjust a reference voltage. The signal variance tracking device enters an offset tracking mode when there has not been any variance occurring in an output of the hysteresis limiting circuit for a predetermined period of time. In the offset tracking mode, the reference voltage selecting device continuously activates a change of the reference voltage until the output of the hysteresis limiting circuit becomes unstable. The unstable state implies that an offset is located, so treatment of the input signals can then be proceeded.

摘要： A filter is disclosed for filtering 2B1Q coded symbols from the set (-3, -1, +1, +3) to obtain convolutions of the form ##EQU1## without any multiplications by three. The convolution is obtained by using two accumulators to separately accumulate coefficients a.sub.j where the corresponding symbol has a magnitude one and where the corresponding symbol has a magnitude three.
