摘要
A converter which may be used for implementing either logarithmic or inverse-logarithmic functions is disclosed. The converter includes a memory, a multiplier, and two adders. The memory stores a plurality of parameters and second-order terms which are derived using a least squares method to estimate a logarithmic or inverse-logarithmic function over a domain of input values. A method of computing the parameters and second- order terms is also disclosed.
