Abstract
PURPOSE: To take a multidigit logarithm analog signal in the digit-selectable form by performing a logarithm conversion by the use of a digit signal and a digital signal of each digit.
CONSTITUTION: The counter 1 which counts the input pulse IP, takes digit signals T1 to T4 and digital signals S1 to S8 that show counting values of the respective digits repeatedly, digit directive dircuits 3 to 8 which feed signals T and S, and form a digit directive signal corresponding to the maximum digit signal T containing the signal S, circuits 16 to 27 which feed signals T and S, weight the maximum digit signal S detected in the digit directive circuit, and reduce the weighting extent for lower digits to 1/10 sequentially to form a weighted signal of significant digits, and circuits 32, 33 which convert the significant digit weighted signal logarithmically are provided. The digit directive signal and weighted signal are added to obtain an analog logarithm output.
