ABSTRACT:
A multi-valued signal decoding circuit is disclosed which has a circuit for detecting a bit synchronization signal included in the multi-valued data signal transmitted in the form of a packet signal, a circuit for detecting by this detected output a timing of a transition of the bit synchronization signal, a circuit for sampling and holding the bit synchronization signal by using sampling pulses generated on the bases of said timing, and a circuit for decoding the multi-valued data signal by using decoding reference voltages formed on the basis of the sampled and held level.
