A logarithmic mixer circuit in the form of a conversion circuit for mixing digital representations of logarithmic values eliminating the usual mathematical processes of determining anti-logs, summing them and then determining the logs again, the invention using addition, subtraction and a look up table. Additional utiity is obtained by the use of scaled offset representations of logarithmic values for digital processing and separate representations for zero values. Also the final output values are limited to the range of the inputs in anticipation of further processing.
