hey
psoc designer 5.1 (CY8C27643-24PVXI)
i would like to know if BPF2 (Two-Pole Band Pass Filter) and INSAMP (Three Op-Amp Topology) can help me to :
1-BPF2:to filter square voltage (input) to have sinusoidal voltage (output) .
2-INSAMP: subtract two tension ( sinusoidal voltage(output of BPF2) - square voltage(input of BPF2) )
if there are any problem,help me to correct.
thanks

You can use BPF2 and INSAMP (Three Op-Amp) to find the difference between a square wave voltage and its equivalent sine wave (or its fundamental frequency). A BPF4 will be more accurate than a BPF2.
For BPF2, the center frequencies can range between 20Hz and 200kHz, while for the BPF4 it ranges between 20Hz and 150kHz.

thanks, but it's impossible to connect the output BPF4 or BPF2 to the input of INSAMP ?
