Скачать или смотреть Is an integrator the same as a low-pass filter? Exploring Analog Synthesis, ep. 7a

In my recent video about op-amp integrators, a viewer asked, 'isn't an integrator just a low-pass filter?' In this video, I try to answer that question. I compare schematics of an integrator and a low-pass filter, build them both on the breadboard, test them over the audio frequency range, and compare their frequency response in both amplitude and phase.

Conclusion: No, they're not the same.

As always, all source code and schematics are on the project GitHub:
