Frequency charactersitics of multistage decimation or interpolation filters

2 views (last 30 days)
I want to display frequency characteristics of filters forming multi-stage chain of decimation or interpolation FIR filters. Frequency characteristics X axis defaults to Fs/2. But in my cases every filter in chain has different sampling frequency Fs. I would like to display charactaristics of my all filters with X axis normalized to highest Fs/2 in my change. Can you show example how to do this in Fvtool and in Matlab
