remember you are looking at the RRC filter..which is only 1/2 the
picture

pass this output though another RRC filter so that you have the full
RC filter and you will see what the receiver sees...

the Rx and Tx have matched filters and the NYquist filter is both of
them in cascade,

you are looking 1/2 way through the cascade..
