in the case of FM,higher frequencies are more affected by
noise than the lower ones.so,if the higher frequencies were
to be artificially boosted before transmission and
correspondingly cut at the receiver,the effect would be that
the signals would be much more immune to noise.this
artificial boosting is called pre emphasis and the
corresponding compensation at the receiver is called de emphasis
