Digital Systems

Digital systems store, process and transfer information in digital, or more specifically binary, form. A bit is a binary (base 2 having only two values one or zero) number. Computers are a common example of a digital system.

Digital signals are more straightforward to transmit due to being less susceptible to interference and noise. The number of bits used to encode (quantization) allows for a higher resolution as illustrated in figure 1.

The https://ifarealtors.com/digital-systems/ majority of digital systems are built using a combinational logic circuit whose output depends solely on its current inputs. State machines are the circuits. The logic of a state machine can be represented by simplified representations known as state diagrams, which facilitate design and testing.

Software can be used to program a digital device to perform a specific function. This is done by replacing the general purpose digital processing element (hardware) by a new prescriptive software program. This flexibility lets digital systems extend their capabilities without having to upgrade their hardware. Many digital systems also have peripheral devices that can be connected to them to increase their functionality (e.g. printing equipment is connected to a laptop in order to expand printing capabilities).
