Hello...
I`m very disappointed with the SystemView!!!
My satellite system simulation requires a narrow bandwidth and consequently a I&D filter at the Earth Station.
I have tried for 1 month simulate this system, but I can't get a good result.
Even using a FIR filter (with no group delay distortion = linear phase) I got a big degration.
I think that the I&D filter isn`t the "real" I&D filter, because it doesn`t dump the signal at the end of integration windows.
In this case, the filter works properly with no limited band, whylst when we limit the band it doesn't work.
I am sending a example of a filter in attachment.
Please ...I need help!!!
