System structure to find the DNA power spectrum S ( n ) by extracting successive sliding windows of the symbolic DNA sequence, mapping each to γ numeric sequences, finding their DFT’s at $\mathit{k}\mathbf{=}\frac{\mathit{M}}{\mathit{R}}$, and finally adding the corresponding squared magnitudes. In this example, N _w  = ⌈(N − M + 1)/R⌉ = ⌈(12 − 6 + 1)/3⌉ = 3 windows are generated.
