Analogue = continously increasing or decreasing.

Digital = increase in steps of 0.01
Thanks but in the mark scheme it says digital increases or decreases by one unit.

Show all the formulas you use.

Show ALL workings (you can still get marks for wrong answers)

Be CALM and READ the question.

When writing long answers; GET TO THE POINT !!! BE CONCISE !!!!!

Hey angl, u can only use one NOT gate. So ur diagram is incorrect. You should connect the NOT to the electrical sensor and the AND is correct
