Textbook chapters 3 starting from and including section 3. 5, chapters 4-6. Concepts: fourier series: decompose arbitrary periodic continuous-time signals, x(t), into sinusoids, synthesis equation, analysis equation: x(t) = akej 2 k. T tdt: be able to use transform properties of fourier series, ctft: decompose arbitrary aperiodic continuous-time signals, x(t), into sinusoids, synthesis equation, analysis equation: x(t) = 1: dtft: decompose arbitrary aperiodic discrete-time signals, x[n], into sinusoids, synthesis equation, analysis equation: x[n] = Xn= : x(ej ) is always periodic with period 2 .
