H[w]==Log[... is not an assignment!
Try
H[w_]=Log[..
and
Plot[H[w],{..

Hope this helps,

Hello.

Simple question - after definition of a functions
which looks like this "H[w] == Log[10, 1 + Exp[I2Pi w]]"
I try to Plot[] it and get the "... not machine size real
number at ..." error. After reading lots of manuals and
postings I came to a conclusion that it should be somehow
related to Evaluate[]/Hold[] problems, but none of these
manuals gave a solution to this problem.

Any1 can help me ?
