Applications of log and antilog amplifier:
The log and antilog amplifiers are very useful in the analog computer. Using these amplifiers it is possible to perform the mathematical operations like multiplication, division, and finding roots and power.
These circuits are also useful in signal compression. (For enhancing or reducing the dynamic range of the signal)
This video will be helpful to all students of science and engineering in understanding the log and antilog amplifier circuits and its usefulness in various applications.
