Hi every one
Please I am trying to design band pass filter using sallen & key filter for the sum of the left audio the frequancy range of which is 23KHz to 53KHz
Please I need to understand the calculation baesed on Fc=1/2piRC as I ahve to use equal values for Rs and equal values for C
*pass band gain = 0
*Gain flatness error = 1dB
*Attenuation at twice the cut-off frequancy 12dB
the sallen key filter should be secound order filter and I dodnt know how many secound order filter I'll need
Many thanks
