MEC3481 DIGITAL ELECTRONICS
3 Credit Hours
This course is open to high school and post-secondary level students.
MEC 3481 - Digital Electronics (3 hrs.)
The student will analyze, construct, test, and interface fundamental digital circuits including logic gates, combinational logic circuits, flip-flops, counters, encoders and decoders, shift registers, arithmetic circuits, digital to analog conversions, and analog to digital conversions. The student will also demonstrate knowledge of numbering systems and integrated circuit specifications.
This course is designed to help the student increase their knowledge regarding fundamentals of manufacturing digital electronics.
Upon completion of the course, the student will be able to demonstrate a proficiency in practical skills required to design and troubleshoot actual digital circuitry that they will see on the job.

Maximum class size:
Based on classroom occupancy.
Course Time Frame:
The U.S. Department of Education, Higher Learning Commission and the Kansas Board of Regents define credit hour and have specific regulations that the college must follow when developing, teaching and assessing the educational aspects of the college. A credit hour is an amount of work represented in intended learning outcomes and verified by evidence of student achievement that is an institutionally-established equivalency that reasonably approximates not less than one hour of classroom or direct faculty instruction and a minimum of two hours of out-of-class student work for approximately fifteen weeks for one semester hour of credit or an equivalent amount of work over a different amount of time. The number of semester hours of credit allowed for each distance education or blended hybrid courses shall be assigned by the college based on the amount of time needed to achieve the same course outcomes in a purely face-to-face format.
