Could you please tell me the code for the following question so as to execute in matlab !

a) print out of values of the first coefficients, Dn for -2 < n < 2

Dn= {(-1+j*2*pi*n)/(1+4*pi*pi*n*n)} (e^-1 - 1);

b) plot the original periodic function xp(t) = x(t+nT), where, T=1, and -2<n<2 and x(t) = exp(-t), 0<t<1;

c) plot the original periodic function versus the synthesized waveform

x(t)=Do+{2(summation)n=-2} Dn e^jnWot;

d) plot the original periodic function versus the synthesized waveform

x(t)=Do+{9(summation)n=-9} Dn e^jnWot;

So you are asking us to do your homework? Why not make an effort? After all, it is you who needs to learn, not us, and you learn by trying, not by being given a free ride.

If you do try it, and you have an actual problem, then ask a question, that indicates you did make an effort. Show what you tried, and what went wrong.
