| Zusammenfassung: | PURPOSE:To adjust an output signal level without losing a compression function of a compressor by providing a signal adjustment means increasing a signal outputted at the compression of the compressor means over the entire level by a prescribed level. CONSTITUTION:A compressor means 2 compresses a high level signal of an input signal VIN. A signal level adjustment means 3 raises an output signal VOUT of a signal processing circuit 1 in the compression operation of the compressor means 2 over the entire level range. The increase VUP is made coincident or correspondent with a compression quantity VCOM by the compressor means 2 preferably. Thus, a level of a maximum value Vmax of the output signal VOUT of the signal processing circuit 1 is made always constant regardless of the operation of the compressor means 2. |
