Which is better, Analog or Digital controller? with comparison and solid reasoning.?

Of course it depends upon the application in question. \n\nYou use a digital controller if you just want to be able to control something in an on off way.\nExamples\nThe numbers on a telephone - why would you ever want to only half press the number down?\nThe big red button that launches a missile - you can't "half" launch a missile.\n\nAnalogue control is used when you want gradation in the amount of controlling. So, the steering wheel of a car is an analogue controller because you're not going to have much control if you can only turn completely to the left or completely to the right.\n\nI'm guessing your after something more specific, which means you're gonna have to ask a more specific question!

Well all are pretty good, i would recomend AIM triton just because the user interface is very simple to use. hope this helps.

Need to have common mode noise rejection on the front end. \n\nLeads should have a ferrite bead or torus around a cable to prevent radio frequency interference from being transmitted down the wire.\n\nAliasing:\nTo avoid aliasing, the input to an ADC must be low-pass filtered to remove frequencies above half the sampling rate. This filter is called an anti-aliasing filter, and is essential for a practical ADC system.\n\nDither:\nIn A to D converters, performance can be improved using dither. This is a very small amount of random noise (white noise) which is added to the input before conversion. Its amplitude is set to be about half of the least significant bit. Its effect is to cause the state of the LSB to randomly oscillate between 0 and 1 in the presence of very low levels of input, rather than sticking at a fixed value. Rather than the signal simply getting cut off altogether at this low level (which is only being quantized to a resolution of 1 bit), it extends the effective range of signals that the A to D converter can convert, at the expense of a slight increase in noise - effectively the quantization error is diffused across a series of noise values which is far less objectionable than a hard cutoff. The result is an accurate representation of the signal over time. A suitable filter at the output of the system can thus recover this small signal variation.\n\nSampling Rate:\nSince a practical ADC cannot make an instantaneous conversion, the input value must necessarily be held constant during the time that the converter performs a conversion (called the conversion time). An input circuit called a sample and hold performs this task—in most cases by using a capacitor to store the analogue voltage at the input, and using an electronic switch or gate to disconnect the capacitor from the input.

Pretty sure yes. If anything, digital would be easier to spy on than analog.

Analog: a device in which data are represented by continuously variable, measurable, physical quantities, such as length, width, voltage, or pressure. In computer terms its voltage. in otherwords an analog signal can be 1,2,7,8.12,31 volts etc. in digital computers the value is off or on (usually thought of as 0 or 1) and represented by a voltage of 0 volts or 5 volts.. 0 being off (0) and 5 volts being on (1) some digital electronics work at a lower 3.3 volt for on but its the same thing 3.3 volts = on (1). so when you see something like 10110111 which is 8 bits or a byte in computer terms the computer has some electronics part inside it that actually has 5volt,0volt,5volt,5volt,0volt,5volt,5volt,5volt on it if you were to mesaure it with a meter. Most computer parts are simple on and off swithes called transistors and the thing that makes them amazing is that there can be millions of transistors on a single chip all going from 0 volts to 5 volts as things happen in the computer.

We had pneumatic instrumentation in our mill for a long time, and still have some that are pneumatic, but we are using DCS in all systems as they are installed.  The biggest problem in pneumatic is that all instruments now being made are electronic - the old pneumatic instruments are obsolete, and if you can find someone to repair them, the price is high.\n\nSome of the advantages we have of the DCS is that the instruments are more accurate, more stable, easy to configure, and can be easily controlled from a workstation. You can do trend analysis, controlled startup/shutdown, and automate routine functions. Just a few advantages...

I am not a physicist, I am an electrical engineering student.  I prefer the degital multimeter over analog due to the fact that the  the digital display directly indicates a quantity as a number, there is no risk of parallax causing an error when viewing a reading.  Similarly, better circuitry and electronics have improved meter accuracy. Analog meters might have basic accuracies of five to ten percent. Modern portable DMMs may have accuracies as good as ±0.025%, and bench-top instruments have accuracies in the single-digit parts per million figures.

Advantages compared to what apparatus?? Please be precise...

Laser is supposedly better, but my optical mouse works GREAT, so I wouldn't need one. Optical just uses a red light, laser uses ... a laser for better precision.

tube amps are louder, as they have a much higher headroom ( it is analog vs digital) but they cost way more.  they also require more maintenance, as tubes need to be replaced regularly, but they have a much cleaner, more natural sound.  solid state is maintenance free, cheaper, and more cost-effective.  it is digital, essentially, and has a lower headroom, making it quieter.  tube amps take a while to warm up, where solid state is reaady cold.  \n\npersonally i would take tubes, if money weren't an object; but since it is, i have solid state.

well,\n\nif you meant what technology should you be using, then i recommend using FM or Bluetooth; each have some pros and cons!\n\nFM is cheaper to implemet, but harder to implemet, bluetooth (lets say 2 serial bluetooth adapters) are more expensive but much much easier to implement... specially with digital signals!\n\nif you ccan edit or give more information about what you want maybe i can help you more!

Yeah you can use a controller, but I think the general consensus is that mouse/keyboard is more accurate.

static implies memeory that does not lose information when power is removed.\nI have never heard of micro-controllers refered to as "static chips"\nMIKE

Disagree. Computers don't make you a better decision maker, they just give you more information to make those decisions.

There is often a wide divergence between theory and application.  I remember one application where lengthy mechanical linkages and cables were used to transmit rudder position for a huge seagoing ship in the even that the steering gear room became flooded (and electronic indication was lost).  The system had too much lost motion to indicate rudder position even though it looked good in theory.  I suggested connecting a vertical rod to the rudders that pierced the overhead into the ("unflooded") compartment above which could be connected to a reliable electronic transmitter (similar to existing "flooded" transmitters) and that worked much better.  Even electronic control systems can exhibit unexpected hysteresis when built.
