so how do i have a Variable or a selector switch that has Chebyshev, bessel, butterworth filters all in one filter?
Do i just have a variable positive feedback parameter and that will give me Chebyshev, bessel, butterworth characterists?
How can i make a filter that will have a mode switch that had the opitions Chebyshev, bessel, butterworth characterists?
Mode switch:
1.) Chebyshev characterist
2.) bessel characeterist
3.) butterworth characterist
how can i do this please?
