Vocational Scenario or
Context
You have been appointed as an engineer trainee in the design and
testing department at Texas electronics which designs and
manufactures electronic devices for use in various industries such as
microcomputers, vehicles, lighting communications, etc for a range of
customers.
Your job involves studying various analogue and digital circuits and
evaluating their benefits and applications.
You are also involved in the study of various digital circuits and
determining truth tables to analyse the output from various inputs
using truth tables.
Your manager has therefore asked you to ca
y out some research
into determining the difference between digital and analogue
electronics, describing simple applications of each.
Task 1
Electronics can be either classified as either analogue or digital.
Each type of design has their own advantages.
Through the study of analogue and digital electronics, your manager
has asked you to answer the following questions:
a) Explain the difference between analogue and digital
electronics. Illustrate your answers with examples.

) Explain the characteristics of a voltage amplifier
1. Gain
2. Frequency response
3. Relationship between Input and source
esistance
4. Relationship between output and load
esistance
c) A logic control circuit in a particular microcomputer was
shown Figure 1. It receive three inputs A, B and C. The
output is used to active memory ICs MEM. Explain the
opertion of the circuit using its truth table, name the logic
function in each case.

d) Explain the benefits (advantages/disadvantages) of using
oth analogue and digital electronics devices using
examples.
e) Critically evaluate the applications of analogue and digital
electronics in terms of their relative advantages, explaining
with examples where each might be applied.

Version 1.0
BTEC Command words:
Typically for a Pass grade you will find;
Describe Give a clear description that includes all the relevant features - think of it as ‘painting a
picture with words’
Define Clearly explain what a particular term means and give an example, if appropriate, to show what
you mean
Design Create a plan, proposal or outline to illustrate a straightforward concept or idea
Explain Set out in detail the meaning of something, with reasons. More difficult than describe or list,
so it can help to give an example to show what you mean. Start by introducing the topic then give the
‘how’ or ‘why’
Identify Point out or choose the right one or give a list of the main features
Illustrate Include examples or a diagram to show what you mean
Interpret Define or explain the meaning of something
List Provide the information in a list, rather than in continuous writing
Outline Write a clear description but not a detailed one
Plan Work out and plan how you would ca
y out a task or activity
State Write a clear and full account
Summarise Write down or articulate
iefly the main points or essential features
Typically for a Merit grade you will find;
Analyse Identify separate factors, say how they are related and how each one contributes to the
topic
Assess Give careful consideration to all the factors or events that apply and
identify which are the most important or relevant
Compare/Contrast Identify the main factors that apply in two or more situations and explain
the similarities and differences or advantages and disadvantages
Demonstrate Provide several relevant examples or related evidence which clearly support the
arguments you are making. This may include showing practical skills
Design Create a plan, proposal or outline to illustrate a relatively complex concept or idea
Explain in detail Provide details and give reasons and/or evidence to clearly support the argument you
are making
Justify How/ Why Give reasons or evidence to support your opinion or view to show how you a
ived
at these conclusions
Typically for a Distinction grade you will find;
Appraise Consider the positive and negative points and give a reasoned judgement
Assess Make a judgement on the importance of something – similar to evaluate
Comment critically Give your view after you have considered all the evidence. In particular
decide the importance of all the relevant positive and negative aspects
Criticise Review a topic or issue objectively and weigh up both positive and negative
points before making a decision
Draw conclusions Use the evidence you have provided to reach a reasoned judgement
Evaluate Review the information then
ing it together to form a conclusion. Give evidence for each of
your views or statements
Evaluate critically Decide the degree to which a statement is true or the importance or value of
something by reviewing the information. Include precise and detailed information and assess possible
alternatives, bearing in mind their strengths and weaknesses if they were applied instead.
