<p>PURPOSE:To easily obtain a complicated conversion characteristic by allowing a storage circuit to store in advance a digital value corresponding to a prescribed function type analog signal in an address of a digital conversion value of an input signal. CONSTITUTION:An analog input signal 1 is converted to an address signal 3 of a digital value by an A/D converting circuit 2, and becomes an address signal of a storage circuit 4. In this circuit 4, prescribed digital values being different at every address are stored in advance, and they are read out successively, inputted to a D/A converting circuit 6 as a digital data 5, and converted to an analog output signal 7 in the circuit 6. Also, the signal 7 becomes the analog signal of a prescribed function. In such a way, a complicated conversion characteristic can be obtained easily.</p> |
