What is analog simulation?

[′an·əl‚äg ‚sim·yə′lā·shən] (computer science) The representation of physical systems and phenomena by variables such as translation, rotation, resistance, and voltage.

What is digital simulation?

a method of investigating real phenomena, processes, devices, or systems that is based on the study of mathematical models with the aid of digital computers. The program executed by the computer is also a kind of model of the subject of the investigation.

What is the difference between analog & digital data?

The difference between analog and digital is in how the information/data is measured: Analog technology uses data that is continuous and the goal is to capture a likeness of reality. Digital technology uses sampling to encode the data and then reproduces it as closely as needed.

What is digital analog simulator?

Digital Analog Simulation (DAS) is a pro- gramming technique which makes a digital computer operate much like an analog compu- ter. The application of the technique to pro- gramming an IBM 7090 computer is described. DAS combines remarkable ease and speed of programming with reasonably high computing speed.

What are different types of simulation?

There are three (3) types of commonly uses simulations: [1]

• Live: Simulation involving real people operating real systems. Involve individuals or groups.
• Virtual: Simulation involving real people operating simulated systems.
• Constructive: Simulation involving simulated people operating simulated systems.

Is a simulation a digital twin?

Actual: A simulation replicates what could happen to a product, but a digital twin replicates what is happening to an actual specific product in the real world.

What is the difference between analog simulation and mixed-mode simulation?

Digital simulation abstracts away important electrical characteristics that might be revealed by the analog simulation. Mixed-mode simulation refers to the simulation of circuits in which analog simulation and digital simulation coexist.

What is the difference between analog and digital circuits?

Digital circuits function on signals that exist at only two levels, i.e., zeros and ones. The design of an analog circuit is difficult, since every component must be positioned by hand for designing the circuits. Digital circuits are very simple to design since the technique of automation can be useful at a variety of levels of circuit design.

What is the difference between analog modulation and digital modulation?

An analog modulated signal can take up any value within a range while a digitally modulated signal can only take up one of a set of discrete values. Analog modulation can produce a signal that carries continually changing information. But, digital modulation produces a signal whose value changes at specific intervals of time.

What is an analog-to-digital bridge?

An analog-to-digital (A/D) bridge translates analog voltage levels into digital states. In addition to connecting elements in the circuit, the bridges play a key role in synchronizing the analog and digital simulators by signaling when new analog time steps and digital events are set.
