(It doesn’t like banging its head!)  \n◆ It can be made to move by being tapped on the back.  \n◆ If it is ignored for a long time, it makes a persistent noise. (It doesn’t like being ignored!) What to do  \n1 Make a list of all the physical signals that the toy will sense as inputs.  \n2 For each input signal, choose an appropriate ‘input’ subsystem that will produce an electronic signal.  \n3 Make a list of all the signals that the toy will produce as outputs.  \n4 Choose appropriate ‘output’ subsystems that will produce the output signals from an electronic signal.  \n5 Draw a system diagram that includes all the input and output subsystems you have chosen anda single ‘process’ block. Label all the signal arrows and all the input and output blocks.  \n6 Write down what the process part of your system has to do. Decide whether the process itself needs to be broken down into more subsystems.  \n7 If necessary, redraw your system diagram to include all the process subsystem blocks.  \n8 Check that all blocks are labelled to describe what they do to a signal.  \n9 Check that all signals are labelled.  \nFurther work  \nIf you have time, model the system you have designed using real electronic subsystems. Check that it works as you intended. If you find that you need to adapt the design as a result of your modelling, record the final design as a system diagram.  \nDownloaded from the Nuffield Design & Technology website: [www.secondarydandt.org](www.secondarydandt.org) Page 2 of 2 SRT 33  \nStrategy SRT  \nUnderstanding system  \ninterfaces  \nPart 1 User interfaces What to do  \n1 Think back to when you used one of the following products, paying special attention to the user interface:  \n◆ washing machine;  \n◆ public telephone;  \n◆ DVD recorder/player;  \n◆ camera.  \nYour teacher may provide you with an alternative product.  \nWhat to write  \nStudent’s Book:  \nConnecting systems to the outside world page 4","cbCaiobbnPGvWMmg","https://ap.wps.com/l/cbCaiobbnPGvWMmg","pdf",1062384,"English","# Strategy - SRT 33-36 - System Think\n## Using system diagrams Part 1: Describing systems\n## Using system diagrams Part 2: Designing systems\n## Understanding system interfaces Part 1: User interfaces\n## Understanding system interfaces Part 2: Operator interfaces\n## Understanding feedback Part 1: Feedback in your freezer","[{\"question\":\"How do you draw a system diagram for a product like a cooker or camera?\",\"answer\":\"Sketch the system, draw a block for each important subsystem, label what each block does, and draw labelled arrows for every input/output signal and for signals linking subsystems.
