摘要
A converterwhich may be usedfor implementingeither logarithmic orinverse-logarithmicfunctions is disclosed.The converter includesa memory (20), amultiplier (22), and twoadders (24 and 26). Thememory (20) stores aplurality of parametersand second-order termswhich are derived usinga least squares methodto estimate a logarithmicor inverse-logarithmicfunction over a domain ofinput values. A method ofcomputing the parametersand second-order termsis also disclosed.
