Hi folks!
We are implementing a chain of FIR filters, all with the config in the attachement but different coefficients!
Sadly after the first FIR filter (if we test with a "chain" of just one filter) we are experiencing an attenuation of approximately factor 32 which would mean that something with the fixed point arithmetics is off by 5 bits. But no matter how I try, I cannot seem to find the mistake ...
Can anybody with some more experience help me spot the hopefully obvious mistake?
Thanks in advance
