When reading the needle on an analog meter, you can get a slightly different reading depending on the position of your eye relative to the needle and the scale behind the needle. This is parallax. The digital meter reads the exact value measured (to the accuracy of the meter), and then displays it in the form of "numbers" or "digits" so your eye is not interpreting the value from a scale.

What are Disadvantages of digital control?
Unwanted Errors of precision when the analog signal is converted into a quantized, sampled digital signal. The same error arises when the digital signal is then converted into an analog signal for the plant to use.
What are advantages and disadvantages of digital signal processing?
Adv. Digital · easy to store and use, that is why computers use it. · Digital data is designed and artificially created, so it is efficient. · Less expensive . DSP is easier to reconfigure as it is made up of h/w as well as s/w. Disadv. Digital · Digital communications require greater bandwidth than analogue to transmit the same information. . Due to Quantisation , an error is alwz there.
What is the input resistance of an ideal current-measuring DMM?
First of all, DMM stands for Digital Multimeter. The -multi implies the meter measures several different parameters, usually voltage, current, resistance, and sometimes other things such as frequency. The input characteristics of a DMM will be very different depending on the parameter selected. For current, the ideal meter would have zero input resistance. Since the ammeter is inserted in series with the circuit under test, any resistance will alter the measured current, introducing error in the measurement.
Why is it important for Boolean expressions to be minimized in the design of digital circuits?
1.to make circuit to be smaller hence less number of logic gate. 2.reduces propagation. 3.reduces error. 4.implementing the expression in circuit form.
Parallax error is a problem that encounter when using a Digital camera?
Film Camera is the correct answer.
What camera causes parallax error?
The parallax error happens when you take a picture using your digital camera and the picture does not appear to look the same as it did in the viewfinder. The cameras that may have this error occur are the twin lens reflex cameras and cameras that include viewfinders.
Give an instance or a situation that describe a parallax error?
When aligning the crosshairs of a rifle scope with a target, if the shooter's eye is not directly centered behind the scope, a parallax error can occur. This causes the crosshairs to appear off-target even though the rifle is aimed correctly. Adjusting the parallax on the scope can help eliminate this error.
What is an parallax error?
The difference between an actual correct view and a displaced visual parallax error
When was Parallax Error Beheads You created?
Parallax Error Beheads You was created on 2008-10-20.
What are the advantages of analog multimeter over digital multimeter?
The main advantage of a digital multimeter over an analog multimeter is their accuracy.AnswerDigital instruments are not necessarily more accurate than analogue instruments (although they often are), but they are far more robust and, usually, far easier to read without error. A digital multimeter has no moving parts and is unaffected by gravity, so they can be used at any angle, whereas analogue instruments needed to be placed on horizontal surfaces and not subjected to vibration.

Does parallax error occur in vernier callipers?
No
What exacly is a parallax error?
A parallax error is when the experimenter reads or record incorrect measurement of a quantity.This may happen because he/she does not know how to read the instrument and can be prevented by learning to read the instrument correctly.
What are the types of random error?
Random errors can be parallax and from changes in the environment.
The surface of a liquid in a graduated cylinder should be read eye level to prevent a ------ error?
This is called parallax error.
Why should you avoid parallax?
There is no such way to avoid parallax error, you just have to be careful.. :)
