- What C2 condenser stands for? What is doing in the circuit? Is that value correct for my purpose?
- I was also looking to how change R value with a pot but I found out that with lesser R value in RC circuit, Freq.Cut value is highier. Which circuit invert the behaviour of resistances?
All material you can suggest me on web is welcome, also about designing more complex filters (2/4 poles - with adjustable resonance / analog filters driven by pwm arduino signals etc. etc.)
