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 & 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

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

Baseband signal Sampling – Fourier Transform of discrete time signals (DTFT) – Properties of DTFT - Z Transform & Properties

UNIT V

LINEAR TIME INVARIANT-DISCRETE TIME SYSTEMS

12

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

TOTAL: (L:45+T:15): 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
