If you're referring to the difference in file size, it's 4096 bytes, which probably just means there was a little data left in a buffer that didn't get pushed through when the flowgraph was done. A FIR may also eat some number of samples (not sure about this).

If you're referring to the signal itself, there's no way you'll get an exact copy back after passing the signal through a filter.

Hi ,
I am trying to implement BPSK transceiver system on a USRP  without
the predefined blocks . I am currently testing my design using a file
source ( as shown in the attachment) but i am not able to receive the
same at the output . Can somebody help ?
Will implement the Costas Loop and other advanced things on the receiver later .
