Is there a block that I can use to model a filter in Simulink, with a given frequency response and groip delay, such as the IMUX, OMUX filters used in the satellite business.
The data for these come as normalized data files, usually as Excel, with three columns, 1. frequency offset from center, 2. Amplitude (rejection) and 3. the group delay in time.
Thanks for pointing me in the right direction. - Charan Langton

One choice is to use a block called Arbitrary Response Filter
A second choice could be the usage of a simulink block called Digital Filter Design
The bad news is that these blocks work only if the appropriate license is available (signal processing blockset)
