ACTIVE_BUTTERWORTH_R_C_FILTER

Published:2009/7/14 3:56:00 Author:May | From:SeekIC

Article gives design procedure for selecting R and C values for active filters characterized by zero output either at zero frequency or at in infinite frequency. Symmetry of network transfer function allows choice of values by coefficient matching technique. Fifth-order low-pass filter, down 50 db at 70 cps, is shown.-R. E. Bach, Jr., Selecting R-C Values for Active Filters, Electronics, 33:20, p 82-85.
