As the name suggest low pass filter circuits are designed to pass or conduct a preferred range of frequency lower or below a desired cut-off threshold, and attenuate or gradually block the frequencies above this value. Normally opamps are employed for making such filter circuits, since opamps are best suited for these applications due to their extremely versatile …
