Hello,
I am currently working in class with a microcontroller. As we are using a microphone we needed to design a low pass filter. I know that there are two different types of filters I can use (Rauch or Sallen Key). Our teacher recomanded using a Rauch filter, however, he didn't explain why.
Could anyone explain the main differences between the two types of filters?
What is the upside of using a rauch filter instead of a Sallen Key filter ?
Thanks for your help.
