Abstract
A converter which may be used for implementing either logarithmic or inverse-logarithmic functions includes a memory, a multiplier, and an adder. The memory stores a plurality of pre-computed values which are used in an interpolation to estimate a logarithmic or inverse-logarithmic function over a domain of input signals.
