Brief information about the techniques to be used in the experiment will be given.

The stages of the design problem and what will be done in these stages will be specified. (state diagram, state tables, state assignments, output and state equations, implementation with gates and flip flops and so on.)

Material equipment list to be used in the implementation of the experiment will be provided.

In the section where the test result will be explained, the student will be asked to comment on the results of the experiment.
