Analog Electronics Operational Amplifier Applications

An antilog amplifier produces an output related approximately to?

AThe exponential of its input
BThe derivative of its input only
CThe average of two supplies
DA fixed digital code

Correct Answer: A. The exponential of its input

Explanation: By placing an exponential junction in the input path and using linear feedback, the circuit can generate an exponential, or antilogarithmic, transfer.
