ENG06073 2019 Analog Electronics

Identify, explain and use fundamental analog electronic components in typical small signal circuits including the resistor, capacitor, inductor, diode, transistor, various power sources, op-amp and 555 timer.

Describe the operation of fundamental small signal analog circuits including R, RC, RL, RLC circuits, voltage, current divider circuits, 

Calculate values for and demonstrate circuits employing amplification and oscillation methods/techniques such as Op Amps, the 555 timer and/or other oscillator circuits

Distinguish between and explain the various forms of small signal a.c. and d.c. voltage regulation including transformers, diode circuits and regulation ICs.

Sketch and construct various small signal transistor circuits using switching and amplification techniques.

Learning should be as active to give the learner the ability to viaualise how the various components work and interact together with various small signal inputs and outputs.

Consideration could be given to:

A lecture giving the week's concepts.

A problem based learning lecture in a flat room which would allow learners to see/demonstrate simple circuits based on 9V battery power supply.  This will allow the learners to get familar with the concepts in a practical way and would speed up the performance in the lab.

A 2 hour lab on the concept of the week.

An end of semester written exam, in term quzzes/test and lab assignments will be given to assess the module.

A repeat exam during the Autumn sitting will be made available.
In addition, an opportunity to submit repeat assessment work will be available for the Autumn sitting.

The emphasis should be on understanding, design, build and usage of analog circuits in a practical manner.  Theory is obviously needed to calculate
