Abstract :
The use of homomorphic filtering in many problems involving nonlinear combination of signals requires complex logarithmic converters. A fast algorithm for digital logarithmic conversion is developed which uses simple computer manipulations. The algorithm trades accuracy for speed, but is found to be adequate in a number of applications tested so far.
