## Homework Statement

Use Matlab to construct a signal of length 2^13 = 8192 that contains only three frequencies:

*x=0.5*sin(2*pi*200*t)+0.2*sin(2*pi*455*t)-0.3*sin(2*pi*672*t)*Compute and plot the absolute value of the DFT.

What does the question mean by signal length and why is it expressed in powers of 2 ? x is clearly my signal but how do i define its length ?

Thanks
