Linear/Analog vs. Digital Integrated Circuits (ICs)

Linear ICs (LICs) also referred to as analog ICs are characterized by inputs and outputs that can take a continuous range of values. In addition, the outputs are generally proportional to the inputs. On the other hand, Digital ICs contain … Read more

The Principle of Operation of a Digital Frequency Meter

A frequency meter/counter is a digital instrument that can measure and display the frequency of any periodic waveform. Its operation is based on the principle of gating the unknown input signal into the counter for a predetermined time. For instance, … Read more

Multiplexers and Demultiplexers in Digital Circuits  

Multiplexers and demultiplexers are devices that route signals. A multiplexer also called a data selector takes one of several inputs and connects it to a single output. The input line that is connected is determined by the binary applied to … Read more
