Because analog computers do not have to encode and decode from binary, and instead use the physical properties of electricity directly, the functions they can perform are done at a substantial fraction of the speed of light, and are therefore dramatically faster than what even the most powerful supercomputer is capable of. Calculations that are very difficult for a digital computer can be done with great speed by an electric analog computer. == == The problems with analog computers stem from the same electrical phenomenon upon which the computer is based. Just as a digital computer is slower because it has to work in and out of binary code to accomplish anything, analog computers are subject to electrical problems and limitations such as the noise floor of its signals, the finite nature of an electron's charge, microelectronic parasitic effects, temperature issues and non-linearities. It is simplest to look at electric analog computing as an improvement on past analog forms, but still suffering from problems analogous to hydraulic and mechanical computing. Hence digital computers are useful over wider ranges of problem types.
No, most computers today are digital machines. Digital computers operate using discrete binary data, represented as 0s and 1s. Analog computers, on the other hand, manipulate continuous physical quantities such as voltage, current, or mechanical motion. While analog computers were used in the past, the vast majority of computers in use today are digital.
Digital computers work with exact discretely coded representations of numbers.Analog computers work with approximate continuous representations of numbers.Hybrid computers are computers that are part digital part analog.I have used all three types, each has advantages.
built with the same level of technology, analog computers are always faster but less accurate than digital computers. however as little significant work on analog computers has been done since the 1980s, they currently significantly lag behind digital computers in speed.
• digital computers work on discrete data representing quantities by encoding (e.g. integers, coded alphanumeric characters, coded floatingpoint numbers). • analog computers work on continuous data representing quantities by analogy (e.g. voltages, currents, shaft rotation rate, shaft position). • hybrid computers are a combination of digital & analog computers connected together to work as one machine.
Analog computers were first made in the late 1920s, Digital computers were first made in the early 1940s.
Included in this industry are digital computers, analog computers, and hybrid digital/analog computers.
The advantages of an analog watch over a digital watch are that analog watches can be more durable in some facets, than a digital one. Many watch enthusiasts also feel that analog watches are more aesthetically pleasing than digital watches.

The advantages of digital radio over analog radio are digital radios get more channels than analog, they are clearer in sound and signal and have more additional features.

Hybrid computers are computers that exhibit features of analog computers and digital computers. The digital component normally serves as the controller and provides logical operations, while the analog component normally serves as a solver of differential equations.
Digital computers are purely digital, i.e. they use digital(electronic) means to process data. Hybrid computers conversely use both digital and analog technologies.

The basic elements in digital signal processing are an analog to digital converter, digital signal processor, and digital to analog converter. This process can take an analog input signal, convert it to digital for processing and offer an analog output.
