a. All electronic systems have input sensors, processors and an output device. Explain the function of

i. Input sensors

ii. processors.

b. The block diagram below shows an electronic system that can be used as a burglar alarm.

A, B and D are the inputs. The processor contains logic gates X and Y. The alarm is the output device The truth table for the circuit is shown at the top of the next column.

i. Use a truth table to identify the logic gates.

ii. State an input, A, B or D which could be connected to a sensor in order to detect a burglar.

iii. Name a suitable device which could be used as an input processor.
