f)

g)

0.8 0.6 0.4 0.2 -5 4 3201 2 3 45

1.5 0.5 -0.5 -1 -2 400 450 500 550 600 650 700

_{Part A:
%% function [xhat,t]%%%%%%%%
%x should be a vector of length N+1. Be careful while giving the input x. It should be a 1x(N+1) vector.
%sample values: if N=10, T=0.02, then x maybe defined as x=0:N (i.e. 0 to 10, total 11 numbers).
% I have kept precision=100 points per sampling interval. So the output vectors will be of size 1x(1+N*100) each. The +1 %corresponts to time t=0 point.}

_{function [xhat,t]=DAC1(x,N,T)}

_{precision=100;
t=0:T/precision:N*T;
xhat=zeros(1,length(t));}

_{for n=1:N+1
xhat=xhat+x(n)*(sin(pi*(t-(n-1)*T)/T))./(pi*(t-(n-1)*T)/T);
end}
