Hi, In my application I need to implement high order Butterworth Low Pass filter to ~1Hz from 32bits, ~50ksps input signal. How can I evaluate the filter performance and estimate the resources...

Hi,

Yes can use cyclone V device family.

For Knowing the resources you can design a project which is easier way to find resources required.

Or

Use FIR II IP Core Performance and Resource Utilization page 9. and find out resources required.

Hi,

Thank you for your quick response!

According to the FIR II IP I can't implement Butterworth Low Pass filter- only Decimation (and Interpolation and Decimation half-band…not Butterworth). Am I right?
