PROBLEM TO BE SOLVED: To provide a signal processing circuit capable of adjusting a parameter in real time.SOLUTION: According to an embodiment, the signal processing circuit includes a Viterbi decoder, a processing circuit, and an adjustment circuit. The Viterbi decoder calculates a branch metric on the basis of an input signal. In the processing circuit, latency for processing the input signal is lower than that of the Viterbi decoder, and the processing circuit outputs a processing result having a correlation to a processing result by the Viterbi decoder. The adjustment circuit adjusts a first parameter required to calculate the branch metric on the basis of the processing result by the processing circuit. |
