"Chopping" in this context means taking an analog signal and encoding it
onto a known AC carrier.  This is run thru an AC amplifier or other AC
channel, then the original analog signal is reconstructed from the chopped
AC signal.  The carrier is encoded in such a way that the analog signal's DC
can be determined from the chopped waveform.

> What are its advantages in analog measurements?

It allows transmission of analog signals thru an AC coupled channel (or
amplifier) without the loss of the DC information.  This can be useful to
get around offset voltage drift, or when a direct DC connection is
impossible or impractical like when isolation is required.

Yes, I believe I could.  However, this is a well known technique about which
volumes have been written.  From previous posts I know you are a fourth year
EE student.  You will learn much more by spending a little time in your
library and researching this on your own.  I would start by asking your
professors to recommend a reference.
