A sample is a value or set of values at a point in time and/or space.
A sampler is a subsystem or operation that extracts samples from a continuous signal.
A theoretical ideal sampler produces samples equivalent to the instantaneous value of the continuous signal at the desired points.
Theory
Sampling can be done for functions varying in space, time, or any other dimension, and similar results are obtained in two or more dimensions.
For functions that vary with time, let s(t) be a continuous function (or "signal") to be sampled, and let sampling be performed by measuring the value of the continuous function every T seconds, which is called the sampling interval. Then the sampled function is given by the sequence:
The sampling frequency or sampling rate, fs, is the average number of samples obtained in one second (samples per second), thus fs = 1/T.
Signal is a 2009 children's science fiction novel by Cynthia DeFelice. The book was a Junior Library Guild selection for 2009. The novel is about a boy who is bored with his new life in upstate New York and discovers a girl who claims to be from another planet, who has been kidnapped by an abusive couple, and attempts to make a signal to contact her home planet.
A mysterious walkie talkie allows a rookie detective in the 1980s to communicate with a jaded cold case profiler in 2016; with the power of fore and hindsight the two not only solve crimes but prevent them from ever taking place. However a long standing murder case is closer to home than either realises.
"SIGNAL" is a song written by Ma-saya, Joker, Joey Carbone, Lisa Huang and Akira for the second single and second studio album of the Japaneseboy band, KAT-TUN. It was released on July 19, 2006 in Japan, and became the group's second consecutive number one single on the Oricon daily and weekly singles charts.
Release and promotion
The single was released in two pressings - a regular version with instrumental versions of all the songs and a limited edition containing the songs, the music video of the title track and a short film of the making of the music video. The single was used in a commercial for NTTDoCoMo's FOMA "9 Series" cell phone which all KAT-TUN members starred in.
KAT-TUN performed the song on television for the first time on Utawara, a variety talk show where they were already regulars alongside senpaiJun Matsumoto of Arashi, on July 16, 2006. They sung on Fuji TV's Hey! Hey! Hey! Music Champ the day after and made their second appearance on Masahiro Nakai's Utaban on July 20. KAT-TUN performed on Music Station on July 21 and two days later, returned to Utawara where they performed two weeks in a row - the latter performance being a medley of "Six Senses", "Real Face" and the single itself.
Sampler is a compilation album by the English rock band Cardiacs, released in 1995.
The album was intended as a budget introduction to the band's music, and was released as part of the general 1995 reissue of the Cardiacs back catalogue. Each track is taken from a different album in the reissue series. Most of the tracks are performed by Cardiacs, but the album also features two tracks performed by Cardiacs spin-off projects: The Sea Nymphs ("Christ Alive") and Tim Smith's Extra Special OceanLandWorld ("Veronica In Ecstasy"). Sampler features two of Cardiacs' singles/lead tracks - the charting version of "Is This The Life?" and a live version of the title track from the "Big Ship" mini-album.
A sampler is a type of compilation album generally offered at a reduced price to showcase a selection of artists signed to a particular record label. The format became popular in the late 1960s as record labels sought to promote artists whose work was primarily available in album rather than single format, and therefore had little opportunity to gain exposure through singles-dominated radio airplay. Most samplers showcased already-released material so that as well as sampling the artist they sampled the albums from which the tracks were drawn.
Elektra Records
The first record sampler was A Folk Music Sampler released by Elektra Records in the USA in 1954, initially for radio stations and later reissued for retail sales. Jac Holzman of Elektra wrote:
At the time the term "sampler" was mainly used for a demonstration of needlework, and this was the first time the word had been applied to a musical compilation. Holzman was enthusiastic for the format, and Elektra regularly issued budget-priced samplers of its folk catalogue in the USA throughout the 1950s and 60s. In the UK, Elektra's office decided to use issue samplers to try to position the label in the marketplace, and issued the folk sampler Fantastic Folk (1968) before the more rock-oriented Select Elektra (1968). However, these British discs were full price issues.

Sampling and Reconstruction of Signals
Sampling is used to convert continuous-time signals such as sound to a sequence of numbers that can be stored and manipulated with computers and can be transmitted. Reconstruction converts the samples representing a signal back to a continuous-time format for physical presentation, such as creating sound.
published: 06 Jan 2020
Sampling, Aliasing & Nyquist Theorem
Sampling is a core aspect of analog-digital conversion. One huge consideration behind sampling is the sampling rate - How often do we sample a signal so we can accurately recreate it?
This may seem trivial at first, but serious problems can arise if we use a bad sample rate, as this can lead to aliasing - The failure to reconstruct the original signal, causing it to appear as a completely different wave of a lower frequency.
To combat this problem, we have to make use of the Nyquist-Shannon Sampling Theorem, which tells us what sample rate to use to prevent aliasing from happening. Today, we take a look at all these points and see just how they link together, to allow us to have the common sample rates (eg. 44100 Hz) we see today!
