Module Overview

Mathematics 6

The first aim of Mathematics 6 is provide the student with further transform based techniques so as to have completed a broad range of methods for the solution of engineering problems. A second aim of the module is to apply numerical implementations of transforms to sampled signals and data. Finally the module aims to complete the process of putting in place a firm mathematical foundation for future development of the student.
