Derive the following realtions:
a) D F T ( x ( k − l ) ) {\displaystyle DFT(x(k-l))\!}
b) D F T ( e j 2 π l k / N x ( k ) {\displaystyle DFT(e^{j2\pi lk/N}x(k)\!}
c) ∑ k = 0 N − 1 x ( k ) y ( k ) ∗ = c ∑ k = 0 N − 1 X ( n ) Y ( n ) ∗ {\displaystyle \sum \limits _{k=0}^{N-1}x(k)y(k)^{*}=c\sum \limits _{k=0}^{N-1}X(n)Y(n)^{*}}
