SYLLABUS

Unit-1:

Classification of Signals and Systems Standard signals, Step, Ramp, Pulse, Impulse, Real and complex exponentials and Sinusoids Classification of signals – Continuous time (CT) and Discrete. Time (DT) signals, Periodic & Aperiodic signals, Deterministic & Random signals, Energy & Power signals – Classification of systems – CT systems and DT systems – Linear & Nonlinear, Time-variant & Time-invariant, Causal & Non-causal, Stable & Unstable.

Unit-2:

Analysis of Continuous Time Signals Fourier series for periodic signals – Fourier Transform – Properties – Laplace Transforms and properties.

Unit-3:

Linear Time Invariant Continuous Time Systems Impulse response – Convolution integrals – Different Equation – Fourier and Laplace transforms in Analysis of CT systems – Systems connected in series/parallel.

Unit-4:

Analysis of Discrete Time Signals Baseband signal Sampling – Fourier Transform of discrete time signals (DTFT) – Properties of DTFT – Z Transform & Properties.

Unit-5:

Linear Time Invariant-Discrete Time Systems Impulse response – Difference equation – Convolution sum – Discrete Fourier Transform and Z Transform Analysis of Recursive & Non-Recursive systems – DT systems connected in series and parallel.
