Digital systems are a collection of devices designed to manipulate physical quantities or information that only accept discrete values. Electronic devices like calculators, computers audio and video equipment as well as other electronic devices are among the most popular. However they may also be magnetic or mechanical. The biggest digital system that exists is the telephone system.
To convert the physical input to digital signals, an analog-to-digital converter (ADC) is used. The ADC converts an analog input signal to the form of binary data bits which represent the amplitude of a single element of the signal. The ADC could use a sample and hold circuit or other method to generate the binary data. The signal may be stored in an electronic memory. The ADC can also be encoded using a code for error correction during transmission.
Once the data has been stored, it can be processed by a processor. The processing unit performs arithmetic as well as logical operations on the data to perform various functions. The processing unit may comprise the GPU, CPU or other specialized processors.
Digital systems make it easier for workers to communicate and collaborate with colleagues and clients. Digital technology can increase productivity and lower expenses by reducing the cost of office space or travel costs. More than 4 million Americans are now able to work from home thanks to the digital technology.
