REPORT Philbrick/Nexus DC log amplifier- a slip stick in 2.65 cubic inches Quicker than you can operate your favorite slide rule, Model 4350 Log Amplifier will calculate the logarithm of a positive voltage or current, or solve the positive antilog of an input voltage. Model 4351 performs the same functions on negative voltage or current. The combination of two Philbrick/Nexus log amplifiers multiplies and divides. Add scaling resistors and you can compute arbitrarily selected powers and roots. Units are fully temperature compensated for use over wide temperature ranges. Units are fully encapsulated and measure 1.4" χ 2.7" χ .7". They feature fast response and a wide 6-decade dynamic range. Priced well below competition at only $95.
