Abstract
PURPOSE: To enable to convert the analog signal in non-linear performance into the digital signal of linear performance, by the D-A conversion through readout of data from the memory, by taking the output such as counter output as the address instruction.
CONSTITUTION: The D-A converter 13 makes D-A conversion for the output from the counter 15 etc. at the feedback circuit, and the content of the counter 15 is controlled so that the output analog signal of the converter 13 is in agreement with the input analog signal objective for the A-D conversion, to pick up the digital signal corresponding to the counter 15. The memory 14 storing the data corresponding to desired conversion characteristics is provided between the counter 15 and the converter 13, the data is read out from the memory 14 by taking the output of the counter 15 as the address instruction, and it is fed to the D-A converter 13. Thus, even if no means compensating the signal characteristics is provided externally, the analog signal in non-linear performance can be converted into the digital signal of linear performance.
