I'd like to implement three bandpass filters with the CY8CKIT-001 PSOC DEVELOPMENT Kit. I read some information about PSoc filters into the forum and I read the AN2099 application note too, but I'm still not sure that they can be implemented and how would can I do it.

The filter's characteristics are:

Filter1:  Fs=105Hz  Fi=45Hz    B=60Hz   Fr=68,7Hz  Q=1,14
Filter2:  Fs=145Hz  Fi=65Hz    B=80Hz   Fr=97Hz     Q=1,21
Filter3:  Fs=8Hz     Fi=0,5Hz   B=7,5Hz   Fr=2Hz      Q=0,26

If it is really possible to implement these kind of filters, what would be the best method, using DBF blocks, SC/CT o FIR filters?.

Best regards,

Antonio M.

Hello Antonio,

I've read your post since I am also interested in these issue.

I am not completely sure that it's possible implement these three filters. As far as I know, you are allowed to implement only one DFB in one design. PSoC Creator doesn't handle more than one DBF... On the other hand each DFB dispose of 2 Channels independently treated.
