TIME ELECTRONIC BOARDS DIGITAL LOGIC FUNDAMENTALS 1
The design and construction of electronic circuits to solve practical problems is an essential technique in the fields of electronic engineering and computer engineering.
With this board the students can study the fundamentals of digital logic, the theorems of Boolean algebra, the logic functions, the karnaugh’s maps, the logic gates NOT-AND-ORNAND-NOR, the flip-flops and the logic families TTL and CMOS
