This course is one of the main basic courses of electrical engineering major as well as a core course of the computer discipline, also a prerequisite to Microprocessors and Applications, and Embedded Systems. Students can learn both theoretical knowledge of digital electronics and tools: Multisim, Modelsim, and Intel Quartus tool for circuit simulation. Students will learn basic principles of digital system, small scale circuit design on experiment board, large scale circuit design on Intel FPGA kit.
