NOTES: A. Connections shown are for multiplication. For division, Z and Z connections are reversed.
B. Output W may need to be amplified to give actual product or quotient of A and B.
C. R designates resistors of equal value, typically 2 k
to 10 k
.
Multiplication: W = A
B
log W = log A + log B, or W = a(logaA + logaB)
Division: W = A/B
log W = log A – log B, or W = a(logaA + logaB)

NOTE: R designates resistors of equal value, typically 2 k
to 10 k
. The power to which the input variable is raised is fixed by setting nR.
Output W may need to be amplified to give the correct value.
Exponential: W = An
log W = n log A, or W = a(n loga A)
