1. The problem statement, all variables and given/known data When calculating the overall gain of a two-stage pass-band filter, can one simply add the gain from the high-pass filter (R1/C1) to the gain from the low-pass filter (R2/C2)? 2. Relevant equations N/A. 3. The attempt at a solution For example, if the gain from the high-pass filter was -2dB and the gain from the low-pass filter was -5dB, is the overall gain -7dB? My book does not go into an explanation on how this works. I may just set up a test circuit in MultiSim to get a general idea of the output gain w.r.t. the individual gains of the high- and low-pass filters.
