### Syllabus

##### Unit 1

Introduction: Integrated approach for continuous, discrete-time cases.

Signals: Classification of signals, continuous – discrete time; even / odd signals, periodic / nonperiodic signals, deterministic / random signals, energy / power signals: Basic operations on signals: Basic (continuous / discrete) signals – unit step, unit impulse, sinusoidal and complex exponential signals etc. Systems (continuous / discrete): Representation, classification – linear / nonlinear, causal / noncausal, time invariant / time variant, with / without memory – BIBO stability, feedback systems. LTI system response of LTI system – convolution, properties (continuous / discrete) – LTI systems – differential / difference equation representation.

##### Unit 2

Fourier Series: Fourier series – Half range Expansions – Parseval’s Identity – Transform integrals¬ – Fourier Integrals – Fourier integral theorem. Sine and Cosine Integrals. Fourier analysis of continuous time signals and systems: Fourier series for periodic signals – Sine and Cosine Transforms – Fourier transform – properties of continuous time FT – Sampling: Sampling theorem – reconstruction of signal – aliasing.

##### Unit 3

Laplace Transform analysis of systems: Laplace Transforms, Inverse Transforms, Linearity, Shifting, Transforms of Derivatives and Integrals – ROC – inverse LT – unilateral LT – Frequency response of continuous time LTI systems, response of electronic circuits with initial conditions using Lapalce transforms. Z-Transform: Definition – ROC – inverse z-transform – properties – transform analysis of LTI Systems – Frequency response of discrete time LTI systems. Inter relationship between different representations and transforms.
