Quick Answer: What Is Used For Masking?

What is the masking effect?

A large-amplitude stimulus often makes us less sensitive to smaller stimuli of a similar nature.

This is called a masking effect.

In a sound, a small-amplitude quantization error may not be heard if it is added to a strong signal component in the same frequency neighborhood..

What is Bitmask in Java?

It means that when applied to two integers (in binary representation), it will result in an integer where each bit will be set to 1 only if both bits at the same position where 1, else to 0.

Which is the masking agent for complexometric titration?

The determination is carried out using potassium cyanide to mask zinc, and excess disodium salt of EDTA to mask lead and aluminium. The excess EDTA was titrated with standard Mn(II)SO4 solution using Erichrome Black-T as the indicator.

What is masking agent with example?

A masking agent is a reagent used in chemical analysis which reacts with chemical species that may interfere in the analysis. … In sports a masking agent is used to hide or prevent detection of a banned substance or illegal drug like anabolic steroids or stimulants.

What is masking in image processing?

Masking is an image processing method in which we define a small ‘image piece’ and use it to modify a larger image. Masking is the process that is underneath many types of image processing, including edge detection, motion detection, and noise reduction.

What is masking in microcontroller?

Often you are interested only in a particular bits of a register. This may be the input of some sensor or something else. So masking means you reset all the bits that are not required and let the bits under consideration as it is. …

What is the masking?

In recent developmental studies, masking has evolved and is now defined as concealing one’s emotion by portraying another emotion. It is mostly used to conceal a negative emotion (usually sadness, frustration, and anger) with a positive emotion.

What is masking in computer?

In computer science, a mask or bitmask is data that is used for bitwise operations, particularly in a bit field. Using a mask, multiple bits in a byte, nibble, word etc. can be set either on, off or inverted from on to off (or vice versa) in a single bitwise operation.

Which of the following is used as masking agent?

Potassium cyanide is an effective masking agent for large quantities of cations; similarly triethanolamine and 2,3 dimercaptopropanol have been employed in several studies [17-20].

What is bit masking used for?

Bit masks are used to access specific bits in a byte of data. This is often useful as a method of iteration, for example when sending a byte of data serially out a single pin. In this example the pin needs to change it’s state from high to low for each bit in the byte to be transmitted.

What are Demasking agents?

A masking agent is a reagent used in chemical analysis which reacts with chemical species that may interfere in the analysis. Demasking is the process inwhich the masked substance regains its ability to enter into a particular reaction.

What are drug masking agents?

Masking Agents/Adulterants Attempts to “beat the test” usually involve the use of a masking agent. Masking agents function as either an assay-interfering substance or a urine diluent. Adulterant testing is performed for urine drugs of abuse tests.

What are metal ion indicators?

A metal ion indicator is a substance that changes color when it binds to metal ions in solution. Metal ion indicators tend to be polyprotic complexing agents. Xylenol orange (Fig. 18.3) is used for the cobalt titration. This indicator is red when it forms a complex with metal ions such as Co2+.

Is iron a masking agent?

At 70 °C, the amount of coprecipitation increases. Up to 68.75 and 19.60 mg of manganese and iron, respectively, can be successfully masked in complexometric titration. … Iron forms a quantitative Fe – TEA complex almost instantaneously at pH 12.

What is masking and its types?

Measuring of Masking Curves • Basically of 3 types of masking curve measurement : 1) Narrow band noise Masking Tone(NMT). 2) Tone Masking Tone(TMT). 3) Narrow band Noise or Tone Masking Narrow band Noise(TMN).

What does masking feel like?

Some have said masking feels like self-betrayal; others have said masking makes them feel they’re deceiving other people. Risk of autistic burnout. When people push themselves to behave in ways that don’t feel authentic, the result can be an overwhelming feeling of overload, sometimes called autistic burnout .

What is pM indicator?

A complexometric indicator is an ionochromic dye that undergoes a definite color change in presence of specific metal ions. … Complexometric indicators are also known as pM indicators.

Which indicator is used in complexometric titration?

To carry out metal cation titrations using EDTA, it is almost always necessary to use a complexometric indicator to determine when the end point has been reached. Common indicators are organic dyes such as Fast Sulphon Black, Eriochrome Black T, Eriochrome Red B, Patton Reeder, or Murexide.
