I want to use a second order active low pass filter to cut off frequencies over 33kHz . The input is 1.3 Volts peak to peak sine wave of 32 Khz and I want to make it 30kHz of 1Vpp . The formulas for calculating the values on the components of S.O.A.L.P. are for different SOALP than mine . Can someone provide me with the formulas that I need to calculate the values of my schematic or better provide the values and explain
Edit: the op amp is provided 20V in the [+] wire and is grounded on the [-] wire
Edit 2: the formulas I found for other SOALP are on this link http://www.electronics-tutorials.ws/filter/second-order-filters.html
