Boolean Logic

The Boolean logic is the foundation of digital electronics and modern computers. Discover here the principles, how to put logic into electronic circuits and how to apply these circuits to solve specific tasks. » more...


Flip-flops are "smart" electronic circuits. They control lifts, traffic lights and make sure computers never forget a number. Here you find out what makes them "smart", how to set up circuits and where they are used. » more...

Digital Comparator

The digital comparator compares two numbers. Without it microprocessors could not take decisions and it makes communication in a computer at all possible. Find out more here. » more...


An adder adds two binary numbers and forms a key element of any microprocessor. Here you find out how an adder is constructed, handles multi-digit numbers and is used optimally. » more...


A simple counter counts events, but is also capable of controlling microprocessors and automata and to reduce frequencies. Here you find the most important features of counters and their applications. » more...

Shift Register

Shift registers consist of a series of multiple flip-flops in which information is stored and passed on at each clock signal. They are used in running lights, series-to-parallel converters and microprocessors. » more...


A digital multiplexer selects from a number of inputs and switches it to one output. Here you find everything about digital multiplexer and its counterpart, the digital demultiplexer. » more...
