what is meant by the term contrast ratio? what is the contrast ratio ofa T.V?

well, Contrast ratio is perhaps the most misleading and overhyped data when it comes to televisions. In theory, contrast ratio measures the difference between the brightness in the super-bright portions of a screen vs. the super-dark portions. A 1000:1 contrast ratio would mean that a perfectly white pixel is 1000 times brighter than a perfectly black pixel.Thats the theory, anyway. The problem

HOW TO ANALYSIS RATIO?

a financial ratio or accounting ratio is a ratio of selected values on an enterprises financial statements. There are many standard ratios used to evaluate the overall financial condition of a corporation or other organization. Financial ratios are used by managers within a firm, by current and potential shareholders owners of a firm, and by a firms creditors. Security analysts use financial ratios

The i/p S/N ratio of system is 50 and the o/p S/N ratio is 5 the noise figure is - a 250 b 55 c 10 d 45

well, well, Noise Figure is defined as the ratio of signal to noise ratio at the output to that at the input. In other words,NF= s/ni/s/noWhere s/nI is the signal to noise ratio at the input, and s/no is the signal to noise ratio at the output of the device under test. Note that s/n at the output will always be smaller than the s/n at the input, due to the fact that any circuit will only add to the noise

When measuring the characteristics of a small-signal amplifier, say for a radio receiver, one might be concerned with its "Noise..."?

well, It is a measure of degradation of the signal to noise ratio SNR, caused by components in the RF signal chain. The noise figure is the ratio of the output noise power of a device to the portion thereof attributable to thermal noise in the input termination at standard noise temperature T0 usually 290 K. The noise figure is thus the ratio of actual output noise to that which would remain

. Lower the standing wave ratio SWR - a Greater mismatch error b Lower mismatch error c No effect on matching d Moderate mismatch error

In telecommunications, standing wave ratio SWR is the ratio of the amplitude of a partial standing wave at an antinode maximum to the amplitude at an adjacent node minimum, in an electrical transmission line.The ratio of maximum voltage to minimum voltage on a line is called the voltage standing-wave ratio.....If you lower the SWR you will get lower/lesser mismatch error....in telecommunications

What is PE ratio? and what it tells about a stock??

PE Ratio is price to earnings ratio of a stock/indexlets consider a stock of company ABC, whose price is Rs 100 per share.there are 100000 shares of the ABC company.therefore market value known = total profit divided by the number of shares of the company =10 lacs divided by 1 lac = Rs 10 per share.thus price to earnings ratio of the share = price per share / earnings per share =100 / 10 =10.The

What is the Difference between an HDTVs Dynamic and Static Contrast Ratio?

When shopping for a high-definition television HDTV, a significant consideration is the contrast ratio expressed as 10000:1, for example. An HDTV with a high contrast ratio will produce truer blacks and show more detail in low-lit scenes. This should make it quite simple to spot a good contrast ratio, except theres a catch. There are two types of contrast ratios: dynamic and static. Understanding

What P/E ratio signifies? Is the company having higher P/E ratio is better than the company with lower P/E ratio?

What is meant by the term Contrast Ratio?

Contrast ratio is of interest in two situations:1. Cameras: When recording an image video, film, photography2. TVs, Monitors, etc. When choosing or setting up a playback device TV, computer monitor, etc...Contrast ratio is intensity between the brightest white and the darkest black....Contrast Ratio is a measurement of the difference in brightness between the whitest white and the darkest black

what is aspect ratio in TV ?

An images Aspect Ratio, or AR, represents a comparison of its width to height. Notation for Aspect Ratio is normally in the form of X:Y, where X represents screen width and Y represents height dimensions arent important, so long as the ratio between them is correct.In order to make it easier to compare different ARs its common to see the width compared to a set value of 1. Using this convention 4

Which window ACin1.5 ton has highest energy efficiency ratio E E Rin india? which split ACin1.0 ton has highest energy efficiency ratio E E Rin india?

What is the difference between contrast ratio and dynamic contrast ratio?

In camera phones as well as digital cameras, the same principle is used. When the lens is exposed to an object that is to be captured, the light being reflected by the object and its background is detected by the image sensor. This reflected light forms and image which we see on the screen. This ima

or performing fast high accuracy operations on the screen e.g. CAD. Manufacturers only state the response time of their displays and do not inform customers of the input lag value.2 The contrast ratio is a measure of a display system, defined as the ratio of the luminance of the brightest color white to that of the darkest color black that the system is capable of producing. A high contrast ratio is a desired
