The Discrete-Time Fourier Transform (DTFT) and the Discrete Fourier Transform (DFT). Periodic and semi-periodic inputs to an LSI system, the notion of a frequency response and its relation to the impulse response, Fourier series representation, the Fourier Transform, convolution/multiplication and their effect in the frequency domain, magnitude and phase response, Fourier domain duality. System representation through differential equations. Characterization of causality and stability of linear shift invariant systems. Linear shift-invariant (LSI) systems, impulse response and step response, convolution, input-output behaviour with aperiodic convergent inputs. System properties: linearity: additivity and homogeneity, shift-invariance, causality, stability, realizability. Energy and power signals, continuous and discrete time signals, continuous and discrete amplitude signals. Signals and systems as seen in everyday life, and in various branches of engineering and science.
