Can we process data in computers in analogue form?
Absolutely, but those are called analog computers and operate very differently than the way digital computers do.Electronic analog computers long predate electronic digital computers and until the invention of the microprocessor were almost always less expensive than electronic digital computers. In some cases hybrid computers were built composed of a digital computer, an analog computer, and converter circuits so that data could be transferred back and forth between the two computing sections of the machine.The most common type of electronic analog computer was the electronic differential analyzer, but there are many other types that have been built for solving specific classes of problems (e.g. electronic harmonic analyzers, electronic finite element analyzers) via electronic analog means.
What is the difference between analog computers - digital computers - and hybrid computers - give examples of each type?
Analog computers are also called continuous computers, as there are no discontinuities in their computations. A mechanical analog computer might represent variables by rotation rate of shafts, any given shaft can rotate at any speed and will smoothly accelerate or decelerate its rotation as the calculation proceeds. An electronic analog computer might represent variables by voltages, say any voltage between -20VDC and +20VDC with voltages smoothly varying as the calculation proceeds.Bush differential analyzer at MIT, electromechanical, 1929.Norden bombsight, electromechanical, 1930s through 1960s (used in WW2, Korea, and Vietnam!).Various commercial electronic differential analyzers sold from 1950s through 1970s, electronic.Murray/Walker simultaneous equation solver, electronic, 1949.Vacuum operated cruise control in cars, mechanical/pneumatic.Resistor/capacitor 3D mesh water table models, electronic.etc.Digital computers on the other hand have discontinuous states that they jump from one to another.ABC: Atanasoff-Berry Computer, simultaneous equation solver, 1942ENIAC, late 1945UNIVAC IIBM 700 and 7000 seriesDEC VAXDesktops and laptopsBoth of the computers in your cellphoneetc.Hybrid computers are simply computer systems that combine both analog and digital computers together. Usually the digital computer controls the analog computer, reconfiguring it and entering new data each time the analog computer completes one problem, to have it solve a different one.Most were custom "one off" systems built by individual labs or universities by buying a standard COTS digital computer and a standard COTS electronic analog computer, and customizing them to work together as needed.One example of such a machine used a DEC minicomputer and an analog computer to model heat flow from a nuclear reactor fuel rod to circulating coolant. The analog computer was programmed on its plugboard to do a rapid solution through a single radial slice of the system, the digital computer was programmed to enter new parameters into the analog computer for each slice starting at the coolant entrance end of the fuel rod and collect and record the results of each slice. The machine could solve the problem to adequate accuracy much faster and more cheaply than an all digital system or all analog system of the time period.
How is analog computers are more powerful then digital computers?
Digital computer uses discretely coded numbers or symbols (typically in binary, although other codings like decimal and trinary have been used in certain machines). Changes in value are sudden jumps by at least the smallest representable value. Digital computers can incorporate error detecting and/or correcting circuits.Analog computer uses continuously varying signals. Changes in value are smooth and continuous. Analog computers drift with temperature, voltage, component aging, etc. and are very sensitive to noise; any of which can cause undetectable errors.
Who discovered hybrid computer?
Nobody, many were deliberately built (mostly in the 1950s and 1960s) to solve problems that were beyond the capabilities of both digital computers and analog computers available at the time. They were specifically built to divide the problem so as to best take advantage of the speed of analog computers (where precision was not needed) and the precision of digital computers (where speed was not needed). A very common use was to have the analog computer very quickly determine an approximate answer, then have the digital computer start from that value using an iterative technique to successively improve that answer until the desired precision was reached. Alone the analog computer could never get the desired precision and without a good starting approximation the digital computer would be too slow. There is much less need for such things now, mostly because inexpensive modern digital computers are much faster than the fastest very expensive digital computers of the 1950s and 1960s.
What is a hybrid IC?
An analog and digital integrated circuit.Wrong, a hybrid IC is a device composed of individual separate components mounted on a tiny ceramic printed circuit board and encapsulated in a metal case or plastic resin. This is in contrast to a monolithic IC that contains everything on a single semiconductor chip.An IC having both analog and digital functions is called a mixed signal IC.
What is it called when you convert a digital signal to analog?
When you convert digital signal to analog, it is called as an analog signal. The device used is called digital to analog converter.
Why computer is called digital?
There are two basic kinds of computers: analog and digital. An analog computer represents information in terms of some physical parameter (e.g., the distance a gear has traveled), whereas a digital computer represents information in terms of a code composed of discrete states (i.e., "on" or "off"). When numerical values are represented in these ways, an analog computer's physical state corresponds to a point on the real number line, while a digital computer's digits are sharply distinct from one to the next.
What are the five kinds of computers?

How CD players convert digital signal to and analog signal?
There is a device called a digital to analog converter (DAC).
What are basic elements of digital signal processing?
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.
How can you convert the digital to analog or analog to digital?
Buy a new digital ready tv, get a digital receiver Sky or Freeview for your analogue tv
How do you convert digital signal to analogue signal?
There are several devices called digital to analog converters for this purpose. 1s and 0s of the digital signal are used to represent the digital signal in analog form.
How do you connect dvi PC output to lcd dvi input?
You will need a DVI cable. Note that DVI can be a digital signal, an analog signal or both. Look in the manuals the see which the computer and monitor support. It is normally digital, which might be referred to as DVI-D. If analog is supported, it will be called a DVI-A. A DVI connection that carries both will be called a DVI-I. If you find you have a choice, use the digital signal rather than the analog.
Is a telephone analog device?
If you are referring to the traditional PSTN phone, the signals that it receives are analog. If you want to know about VOIP phone, it is digital in nature. However, analog can be converted to digital by using a device called ATA.
What device changes digital computer data into analog data that can be sent over phone lines?
A modem performs this function. A modem converts digital information to analog information to transmit a signal over phone lines. The process of converting this signal in this manner is modulation. They also convert analog information back to digital information to receive data. This is called demodulation. The name modem is a combination of the words modulator-demodulator.
How could a digital signal from outer space be picked-up?
Radio "signals" are always analog, not digital. To send a digital signal, it must be converted to analog format, and then the received signal has to be re-converted to digital. So the Voyager and Viking space probes, for example, include a digital-to-analog converter attached to the radio transmitter, and the radio receivers here on Earth are routed through an analog-to-digital converter to make sense of them. You yourself may have such an "analog-to-digital" converter; they are called "modems", or "modulator/demodulator".
What is the clock with a seconds hours and minutes hand called?
Analog, as opposed to digital.
