As the frequency increases, the gain decreases. This report focuses on active low – pass filter design using operational amplifiers. Active Low Pass Filter with Op Amp. Filter tables are developed to simplify circuit design based on the idea of. The dual op – amp provides two stages , each stage generating two poles of the response.

For a schematic, see . A low – pass filter (LPF) is a filter that passes signals with a frequency lower than a selected cutoff frequency and attenuates signals with frequencies higher than the cutoff frequency. The exact frequency response of the filter depends on the filter design. Another type of electrical circuit is an active low – pass filter.
