Question

Question 1 Digital Electronics and Combinational Logic 1a) Analog and Digital Electronics i. Write either "digital" or "analog" in this to indicate whether the property in that row is - typical of digital electronics or analog electronics. The first row has been completed as an example. Property Digital/Analog Difficult, manual circuit design Analog Continuous valued signals Tolerant of electrical noise Circuit state tends to leak Intolerant of component variations ii. In older cars the timing of the electrical pulses to the spark plugs was controlled by a - mechanical distributor. This contained a rotating contact that was mechanically linked to the rotation of the engine. Newer cars use electronic ignition. Electrical sensors detect the position and speed of the motor and a digital controller sends ignition pulses to the spark plugs. Briefly describe 2 likely benefits of the digital electronic ignition system over the mechanical one. An example is given first. More flexible control: the digital system can adjust the ignition timing more easily than a mechanical one.
