Digital Systems Design
Midterm Exam
Course Introduction
Digital Systems Design introduces students to the principles and methodologies used in the analysis, design, and implementation of digital electronic systems. The course covers fundamental concepts such as number systems, Boolean algebra, logic gates, combinational and sequential circuits, and hardware description languages (HDL) like VHDL or Verilog. Students will learn to design, simulate, and optimize digital circuits using modern tools and technologies, gaining practical experience in constructing modules like adders, multiplexers, flip-flops, counters, and finite state machines. Through theoretical study and hands-on laboratory exercises, students develop the skills necessary to tackle real-world digital design challenges in computer engineering and related fields.
