A signal processing apparatus for performing maximum likelihood decoding using one of a partial response PR(1,1) scheme and a partial response PR(1,0,1) scheme, has a maximum likelihood decoding device which includes a comparison circuit for comparing a branch metric difference supplied from an external circuit and a held past metric difference, a holding circuit for holding, as a new metric difference, one of the branch metric difference supplied from the external circuit and the held past metric difference on the basis of a comparison output from the comparison circuit, and a deciding circuit for deciding decoded data on the basis of the comparison output from the comparison circuit.
