WebbThe shift theorem states that a delay in the time domain is equivalent to a linear phase shift factor in the frequency domain. THEOREM Shift: Let y[n] be the delay of x[n] by m samples, i.e., y[n] = x[n − m] for all n. Then, Y(ω) = e−jmω ·X(ω). The proof is left as an exercise. 3 Properties of Linear Time-Invariant Systems 3.1 Definition
