Solved Design a low pass filter using this op amp circuit Circuit Diagram Active Low-Pass Filter Design Jim Karki AAP Precision Analog ABSTRACT This report focuses on active low-pass filter design using operational amplifiers. Low-pass filters are commonly used to implement anti-aliasing filters in data acquisition systems. Design of second-order filters is the main topic of consideration. The low pass and high pass filter can be combined into a band pass filter. In the examples below the corner frequencies were chosen to be the audio band (20Hz - 20KHz). Notice the difference in the gain outside of the pass band. The gain of the inverting amplifier continues to drop as you get farther away from the pass band.

This circuit is an op-amp-RC resonator: it produces resonance using only resistance, capacitance, and amplification. We could use this circuit to replace the inductor in a second-order RLC (resistor-inductor-capacitor) filter, but instead, we'll look at a simpler and more compact topology known as the Sallen-Key filter. Second-Order Active Active Low Pass Filter Example No1. Design a non-inverting active low pass filter circuit that has a gain of ten at low frequencies, a high frequency cut-off or corner frequency of 159Hz and an input impedance of 10Kฮฉ. The voltage gain of a non-inverting operational amplifier is given as: Circuit diagrams and their building blocks, such as low-pass filters and op amps, may sound complex, but the basics are easy to understand and apply. Op amps are the backbone of many audio circuits, and low-pass filters are one of the most common op amp applications.
So as you can see, there a number of factors that go into creating a low pass filter with an op amp. If you are dealing with high-frequency signals, then it's best to use a much higher-speed op amp than the LM741. For relatively low frequencies, it should suffice. And this is how a low pass filter circuit can be an op amp. Related Resources
