SYNOPSIS:


Central  to  the  profession  of all electrical  engineers  (and  many
mechanical  engineers)  is measurement of electrical  quantities,  or,
more  generally, physical quantities whose values have  been  rendered
electrical  by a transducer.  Such measurements are almost  invariably
made  with  the  aid of electronics, and increasingly by sophisticated
instrumentation   which   provides   multidimensional   displays   and
analytical capabilities.  Automation of such measurements is  also  on
the  rapid  increase.  However, in the face of these developments  the
need to comprehend the physical principles of making accurate, precise
and   trustworthy  measurements,  particularly  of  small  quantitites
(microvolts, microamperes), remains fundamental.

It  is the task of the professional engineer to be able to specify and
evaluate  equipment for a given measurements task;  this  requires  an
appreciation of electronic measurement systems : . at the system level
by  an  awareness of the range, operating   principles and limitations
of  commercial  test equipment; . at the circuit level which  includes
the  effects  and minimisation   of interference and certain  commonly
employed  circuit and IC   configurations such as the Phase Lock  Loop
and  frequency    synthesis;  and . at  the  "hardware"  level,  which
includes the choice of components,   construction, requirements of the
operating  environment (temperature,   vibration) and their effect  on
reliability.

The  professional engineer is also commonly called upon  to  supervise
the  manufacture  of electronic equipment.  Experience  of  electronic
construction practice is therefore required and best gained by  "hands
on"   project   work.   The  principles  of  electronic  manufacturing
including printed circuit board design are presented and the processes
of modern, automated production introduced.

OBJECTIVES:

When a student has successfully completed this unit he/she should be able to :

  1. Select and operate all common electronic laboratory test equipment.
  2. Rapidly acquire skill in the effective use of unfamiliar test equipment.
  3. Recognise the limitations of electronic measurement equipment by means of a knowledge of their operating principles.
  4. Specify, assemble and program automatic test equipment linked via the GPIB.
  5. Know the physical causes and effects of measurement signal interference and recommend appropriate minisation techniques.
  6. Know the range of operational, instrumentation and other amplifiers available, their errors and limitations and be able to select appropriately.
  7. Undertake appropriate "breadboard" construction and testing in low signal/high interference environments.
  8. Explain the operation and application of the Phase Lock Loop and other synchronous detection methods.
  9. Explain the principles of frequency synthesis.
  10. Design simple printed circuit boards and undertake simple mechanical design and simple construction of electronic equipment.
  11. State the major processes of modern automated manufacture of electronic equipment.
  12. Explain the principles of reliability theory as applied to electronic systems, and undertake calculation, which might include composite reliability and subsystem redundancy.
