Using log and antilog amplifiers, the circuit can be built to obtain the output proportional to the product of the two input voltages. The circuit is called analog voltage multiplier.


Analog Voltage Divider Circuit

Similar to analog voltage multiplier, analog voltage divider can be obtained using log and antilog amplifiers. This circuit gives output which is proportional to the division of the two input signals. The circuit for the voltage divider is shown in the Fig. 4.7.1.


Key Point Thus the output is proportional to the division of the two analog inputs V1 and V2
