Objective

This course provides an introduction to applied signal processing. The student is introduced to various

real-life signals, ways of detecting and sampling these signals, simple calculations of signal parameters

and simple ways of processing and manipulating these signals.

Signals and their parameters

What is a signal? Different types of signals; Electrical signals, Acoustic signals, Electromagnetic signals,

vibrations and biological signals.

Signals in Time Domain (TD). View voice signals on an oscilloscope.

Signals in Frequency Domain (FD).

Frequency and time period.

Signals as a summation of sinusoidal waves.

Hand sketching of signals in TD and FD; square waves, saw-tooth.

Examples of signals in computer systems (data on buses) and in

Communication systems (Ethernet signals or mobile phone signals).

Transducers to convert signals into electrical signals:

Acoustic transducers (Microphone and Speaker), Position, Speed, Temperature and Pressure sensors.

Power of signals, Energy in signals.

Simple power and energy calculation in various practical signals.

Signals Processing components

Amplifiers: gain and bandwidth.

Filters: phase and amplitude.

Practical examples in acoustics.

Lab sessions in Signal processing

Measurements on oscilloscope and spectrum analysers.

Use of simple LF filters and amplifiers.

Fourier transform on Simulink

Addition and multiplication of simple signals on Simulink.
