I am a student using the ada2200 as a Lock-in amplifier, the sensor application I am using it for requires a high frequency excitation signal, therefore I want to divide the Fsi by 32 rather than 64. Simply adjusting the value Fsi is divided by is easy however, I also need to adjust the filters coefficients such that the pass band centers on this frequency. Does anyone know what coefficients are required to accomplish this?
