Bandpass active filters with Sallen-Key circuits (5 - Active Filters)

Great video! Where is the table showing the relationship between order and K-value from? It's not a concept i've seen elsewhere.

If you cascade two 2nd order circuits doesn't it make the whole circuit a 4th order?

Awesome. How far the cut off frequencies should be separated to keep this filter stable? I ask this because I wonder if it is possible to make a filter where the cut off frequencies may be adjusted with a potenciometer and those limits should be care. Thank you so much. 🙂

this playlist is insaneeee

Why not just ditch the amplification and use unity gain?

Shouldn't there be high pass first and then low pass in the circuit design?
