Abstract: PURPOSE: An apparatus for decoding a manchester code is provided to decode a manchester code without any error by restricting an accumulated value to a certain range of value. CONSTITUTION: A first sampler(210) samples the data encoded into a manchester code according to a first clock. An accumulator(220) combines the value of the data inputted from the first sampler with an accumulated value. A first comparator determines whether the output value of the accumulator is greater than a predetermined first reference value or not. A symbol clock generator(290) generates a second clock and a third clock. A second sampler samples the data inputted from the first comparator according to the second clock.
