Signals and Systems is an introduction to analog and digital signal processing, a topic that forms an integral part of engineering systems in many diverse areas, including seismic data processing, communications, speech processing, image processing, defense electronics, consumer electronics, and consumer products.

The course presents and integrates the basic concepts for both continuous-time and discrete-time signals and systems. Signal and system representations are developed for both time and frequency domains. These representations are related through the Fourier transform and its generalizations, which are explored in detail. Filtering and filter design, modulation, and sampling for both analog and digital systems, as well as exposition and demonstration of the basic concepts of feedback systems for both analog and digital systems, are discussed and illustrated.

Signals and systems is in Second year  Electronics and telecommunication engineering

Course Objectives:

1. To introduce students to the idea of signal and

system analysis and characterization in time and

frequency domain.

2. To provide foundation of signal and system concepts

to areas like communication, control and signal

Course outcomes are :students will

• Be able to classify different  signals such as the unit step, ramp, impulse function, sinusoidal signals and complex exponentials.

• Be able to classify signals as continuous vs discrete-time, periodic vs non-periodic, energy vs power signal, odd vs even, conjugate symmetric vs anti-symmetric

• Be able to Perform mathematical operations on signals.

• Be able to compute the Fourier Series and Fourier Transform of a signal

• Be able to compute the Z transform  and Laplace Transform of a signal.

• Be able to understand state space analysis and realize discrete time systems.
