P4 describe the interfacing and signal processing requirements of two engine management system components b) Complete the following tasks using annotated diagrams, where appropriate. I. Describe the relevant aspects of interfacing and signal processing requirements of two engine management system components (such as temperature and speed sensors and throttle position/drive by wire actuators). Your response must also cover compatibility between components and systems, the characteristics of devices which mean signal processing is needed and the control of output devices (for example, buffer circuits).
