Thanks!<br /><br />Mistake:<br />Fourier transform written as<br />A_c/2 * m(t) * cos(2*pi*f_c*t) <=> A_c/4 * [M(f-f_c)+M(f-f_c)]<br /><br />Of course, it should be<br />A_c/2 * m(t) * cos(2*pi*f_c*t) <=> A_c/4 * [M(f-f_c)+M(f+f_c)]<br />because a cosine can be expressed as a summation of two complex sinusoids. If this is unclear, expand the Euler representation of exp(j*x) and exp(-j*x) and try to express cos(x) in terms of exp(j*x) and exp(-j*x).<br />wellhereiamhttps://www.blogger.com/profile/17067740844274290145noreply@blogger.comtag:blogger.com,1999:blog-4148295076729951075.post-56402109319816482912013-01-24T07:11:12.678-08:002013-01-24T07:11:12.678-08:00There is a sign error at http://mathbin.net/equati...There is a sign error at http://mathbin.net/equations/147525_0.pngAnonymousnoreply@blogger.com
