OBJECTIVES:
• To understand the basic properties of signal & systems
• To know the methods of characterization of LTI systems in time domain
• To analyze continuous time signals and system in the Fourier and Laplace domain
• 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 & Non-causal, 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

Impulse response - convolution integrals- Differential Equation- Fourier and Laplace transforms in Analysis of CT systems - Systems connected in series / parallel.

UNIT IV

ANALYSIS OF DISCRETE TIME SIGNALS

12

TOTAL: 60 PERIODS

OUTCOMES: At the end of the course, the student should be able to:
• To be able to determine if a given system is linear/causal/stable
• Capable of determining the frequency components present in a deterministic signal
• Capable of characterizing LTI systems in the time domain and frequency domain
• To be able to compute the output of an LTI system in the time and frequency domains
