Design Technology · SL / HL · syllabus-mapped notes

1. DTB3.4.1

   Electronics in everyday products

   Electronics are present in the design of many everyday products.

2. DTB3.4.2

   Specialized apparatus

   Design and manufacture of electronic products requires the use of specialized apparatus.

3. DTB3.4.3

   Ohm’s law and power

   Voltage (V) in a circuit is calculated by a combination of current (I) and resistance (R), and electrical power (P) is calculated by a combination of voltage (V) and current (I).

4. DTB3.4.4

   Series and parallel

   Resistors and capacitors can be used in series or parallel in a circuit for different purposes.

5. DTB3.4.5

   Flow diagrams

   Electronic systems are used to perform a specific function, which can be mapped using a flow diagram.

6. DTB3.4.6

   System diagrams

   System diagrams depict the components and the arrangement of circuits.

7. DTB3.4.7

   Sensing inputs

   Digital systems at the first stage of the input–process–output model use inputs to sense changes in their environment.

8. DTB3.4.8

   Control circuits

   Digital systems at the second stage of the input–process–output model use control circuits to monitor and control.

9. DTB3.4.9

   Logic

   Digital systems use logic to compare input data.

10. DTB3.4.10

    Outputs

    Digital systems at the third stage of the input–process–output model use the output to communicate to or control their environment.

11. DTB3.4.11

    Communicating embedded systems

    Digital systems can communicate with each other using embedded systems.
