Prototype Design

1. The competitor must choose to assemble or design only one complete circuit by choosing from the components supply the competition may design only one of the following items as follows.

1.1 Regulator circuit or

1.2 Speaker protector circuit or

1.3 Pulse generator circuit or

1.4 Any other from the competitor ’s own idea, using the components available.

2. The competition must do as follows ;

2.1 Draw the completed circuit under design.

2.2 Give the name of the circuit design.

2.3 List the components using in the circuit design.

2.4 The circuit under design must do function properly when testing on

the d.c. power supply.
