It is a new block simulink signal library called the Phase Filter.The transfert function is F(p)=(1+T1p)/(1+T2p).Students can change parameters T1 and T2 time constants of filter.The phase filter in automatic control is for Corrector block and also in PLL oscillator application.
I assume you will only do a favor to other users.
BUT please stop spaming the FEX with trivial examples.
I suggest: read the docs of Simulink and you will discover that most of your blocks are contained in the standard distribution.
BTW: implementing a realizable filter by a differentiator makes no sense.
