2 The information sequence {a} is a sequence of independent equiprobable Binary symbols taking values of +1 or -1 . This data sequence modulates The basic pulse g(t). LA, o<+52T The modulated signal X(t) is as follows: gct) To, otherwise X(t)-Zang(t-17) nt х i) ii) Find the power spectral density of X(t). If we use a precoding of the form bn =a +an-1+an-2 ,determine the Power spectral density of Following signal : YLt)- (10 points) ) bng(t-nt) - naudo
