No description available.


This design circuit features overload protection in the input and output. It has adjustable attenuation for more specific frequency trimming. The excess of common mode range value will not result latch-up and other possible type of spikes.

It is comprised of LM741 general purpose amplifier that amplifies the generated signal. The RC circuit is used as bandpass filter that manages the frequency passing through the entire system, in which it does not require equal values of R or C because the reactance of the series RC will be exact multiple of the shunt RC in some frequency values.

The design is applicable to different types of electronics system like several audio system of electronic home appliance. It can be a useful reference to student experiments and testings.
