Hi Namrata,

I think you're mixing up a lot of concepts. A "block" is a software
unit in the GNU Radio framework. Please read the introductory pages of
gnuradio.org to understand blocks better.
A USRP is a hardware device; it does the sampling, which, of course,
is a functionality of hardware. It, in fact, does a lot of signal
processing. To learn about the properties of the USRP devices, read
the website of the manufacturer Ettus and the UHD driver wiki.

The USRP source block doesn't do any "signal processing"; it just gets
the samples from the USRP driver (called UHD) into GNU Radio.

Greetings,
Marcus
