Logarithm Function Generated by Parallel Resistors
April 1969 (vol. 18 no. 4)
pp. 379-381
D. Steinmeyer, Emerson Electric Company Electronics and Space Division
Placing a fixed resistor in parallel with an adjustable resistor will cause the resistance of the combination to vary as the logarithm of the setting of the adjustable resistor over a limited range. Calculated compromises between accuracy and range cover ?0.1 percent over a 2.5:1 range to ?10 percent over a 175:1 range. A table of intermediate values is given.
