Hi Abdeslam, I assume you already have definite formulas that define the estimator for these two numbers. Unless you can directly "click together" that estimator in GRC, you will most likely have to implement it. In many cases, doing this in Python is rather easy (especially if you come from a python or matlab background), so I'd recommend reading at least the first 3 chapters of https://gnuradio.org/redmine/projects/gnuradio/wiki/Guided_Tutorials
