3. Improve the Students’ Ability
We focus on the improvement of the students’ ability to analyzing and solving the
problems. The students are required to read the large scale circuits clearly, understand
the structure and principle of the circuits. They can analyze qualitatively and
calculate the coefficients quantitatively. Cultivate the students’ interests on
experiments and circuit design. Finally, the students can learn the basic requirements
of the circuits design by heart.
