To analyze discrete time signals and system in the Fourier and Z transform domain

UNIT I

CLASSIFICATION OF SIGNALS AND SYSTEMS

12

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 & Noncausal, Stable & Unstable.

UNIT II

ANALYSIS OF CONTINUOUS TIME SIGNALS

12

Fourier series for periodic signals - Fourier Transform – properties- Laplace Transforms and properties

UNIT III

LINEAR TIME INVARIANT CONTINUOUS TIME SYSTEMS

12
