Summary: | In an apparatus for receiving a burst signal intensity-modulated by a signal obtained by Manchester-code converting each code of an input signal into a pair of codes, the received burst signal is converted by a partial response circuit into an AC signal and then AC-amplified. From the received burst signal is extracted a timing signal of the same frequency as the clock frequency of the Manchester-coded signal. In a decision circuit, the AC-amplified output is decided by the timing signal, through using a decision level close to zero, at the timing of each of former and latter codes of the Manchester-coded pair codes. A coding rule violation is detected in a plurality of successive decision output codes to detect a reception abnormality such as asynchronism and a signal collision. The decision output is decided at the timing of the latter one of the Manchester-coded pair codes, thereby regenerating transmitted information. |
