Input, process and output
Learning outcome
Example question
lights
before
I can say that an electronic system
is made up of three parts: input,
process and output.
I can identify from a block diagram
the input, process and output.
Draw a block diagram of the
three main parts of an
electronic system
From the block diagram below,
what is the output device?
microphone
amplifier
loudspeaker
I can draw a block diagram showing
the input, process and output
subsystems of an electronic device.
I can say that the microphone,
thermistor, LDR and switch are
examples of input devices
Draw a block diagram showing
the input, output and process
for a baby’s monitor.
Give an example of an input
device.
I can say that the microphone
changes sound energy to electrical
energy.
I can say that the resistance of a
thermistor changes with
temperature.
I can that the resistance of an LDR
decreases as the light gets brighter.
What is the energy in of a
microphone?
What happens the resistance
of a themistor is the
temperature increases?
What happens to the reistance
of an LDR if it gets dark?

Learning outcome
Example question
I can pick an appropriate input
device for a given application.
I can say that an output device
changes electrical energy into
another form of energy.
I can say that the loudspeaker,
lamp, LED and electric motor are
examples of output devices.
I can say the energy change that
takes place for a given output
device.
I can pick an appropriate output
device for a given application.
What input device would you
find in automatic central
heating?
What is the starting energy for
an output device?
Give an example of an output
device.
What is the energy change for
the following output devices:
(a) LED?
(b) buzzer?

I can draw and identify the symbols
for an AND, OR gates and a NOT
gate
Draw the symbol for a NOT
gate.
What is the logic gate drawn
below?
I can say that:
high voltage = logic 1
low voltage = logic 0
I can say that for a NOT gate the
output it the opposite of the input.
I can say that for an AND gate both
inputs must be high for the output
to be high.
What does it mean when a
switch is at logic 1?
If the input of a NOT gate is
logic 0, what is the output?
Look at the logic inputs for the
AND gate below, what will the
output be?
1
0

I can explain how to use
combinations of logic gates for
control in simple situations.

A student is asked to design a
circuit to remind a car driver
tat the car lights have been
left on after the ignition
switch has been switched off.
A buzzer is to sound when the
lights are on but only when the
ignition is switched off.
The light sensor gives logic 1
when the lights are on.
Draw a suitable block (logic)
diagram of the circuit.
