What is optical fidelity?

Fidelity is therefore a measure of the realism of a model or simulation. In quantum mechanics and optics, the fidelity of a field is calculated as an overlap integral of the field of interest with a reference or target field.

What is your meaning of fidelity?

Image fidelity, often referred to as the ability to discriminate between two images or how closely the image represents the real source distribution. If we cannot detect the difference between a photograph and a digitally printed image, we might conclude that the digital print has photographic image quality.

What does fidelity mean in HiFi?

High fidelity
High fidelity (often shortened to Hi-Fi or HiFi) is a term used by listeners, audiophiles, and home audio enthusiasts to refer to high-quality reproduction of sound. Ideally, high-fidelity equipment has inaudible noise and distortion, and a flat (neutral, uncolored) frequency response within the human hearing range.

Why is fidelity important?

Fidelity is something that is important in any relationship. It is an indicator of the value and trust both partners place in the relationship. There is no right or wrong definition, as long as both people in the relationship agree on the terms and then honor those terms.

What is fidelity in WIFI?

As this break-up would suggest, Wireless Fidelity is a term used to define data technology that allows people access to high-speed internet without the need for cables. Wi-Fi itself refers to the popular wireless network technology which enables a Wireless Local Area Network, or WLAN.

What is a low fidelity photo?

Lo-fi photography (“lo-fi” meaning low-fidelity, referring to “any process which fails to achieve the accuracy and ‘transparency'”) refers to unconventional photographic practices, chosen for aesthetics, which give an impression of low quality.

What is lo-fi film?

Lo-Fi Sci-Fi is an emerging genre of the last decade or so inspired by Mumblecore and budgetary constraints. The name is derived from ‘Low Fidelity’ and ‘Science Fiction’, seemingly meant to convey the low budget, amateur approach of filming a Science Fiction movie.

Is high fidelity the same as stereo?

Because in the early days only fanciers of high fidelity (or hi-fi) equipment could afford stereophonic sound, “stereo” came to be used as a substitute for “high fidelity,” and even “record player.” Stereo equipment (for instance a cheap portable cassette player) is not necessarily high fidelity equipment.

Why is it called high fidelity?

Manufacturers began to call their equipment and records “high fidelity” to help sell them. In the 1950s, “hi-fi” became the popular term, replacing “phonograph” and “record player”. Rather than playing a record “on the phonograph,” people would play it “on the hi-fi”.
