Analog circuits do not involve quantisation of information into digital format.

* Analog sound vs. digital sound

da: Analog og digital

Analog processors operate directly on the electrical signal, while digital processors operate mathematically on the digital representation of that signal.

* Analog sound vs. digital sound

Analog circuits use a continuous range of voltage as opposed to discrete levels as in digital circuits.

Analog computers had an advantage over early digital computers in that they could be used to solve complex problems using behavioral analogues while the earliest attempts at digital computers were quite limited.

Analog synthesizers that have no digital component and were built prior to MIDI's development can be retrofit with kits that convert MIDI messages into analog control voltages.

* Analog sound vs. digital sound

Analog voltmeters move a pointer across a scale in proportion to the voltage of the circuit ; digital voltmeters give a numerical display of voltage by use of an analog to digital converter.

) Analog instruments are usually based on a microammeter whose pointer moves over a scale calibrated for all the different measurements that can be made ; digital instruments usually display digits, but may display a bar of a length proportional to the quantity being measured.

Analog multimeters have the precision and reading accuracy limitations described above, and so are not built to provide the same accuracy as digital instruments.

Analog meters are able to display a changing reading in real time, whereas digital meters present such data in a manner that's either hard to follow or more often incomprehensible.

Analog meter movements are inherently more fragile physically and electrically than digital meters.

Analog signal generators based on a sinewave oscillator were common before the inception of digital electronics, and are still used.

Analog broadcasting on Fox largely ended on June 12, 2009 as part of the transition to digital television.

Analog clocks with digital displays cannot be wound back, as the flip mechanism operates only in one direction.

Despite this, vinyl records remain popular, and discussion about the relative merits of analog and digital sound continues ( see Analog sound vs. digital sound ).

Analog cassette deck sales were expected to decline rapidly with the advent of the compact disc and other digital recording technologies such as digital audio tape ( DAT ), MiniDisc, and the CD-R recorder drives.

These amplifiers use pulse width modulation, pulse density modulation ( sometimes referred to as pulse frequency modulation ) or a more advanced form of modulation such as Delta-sigma modulation ( for example, in the Analog Devices AD1990 class-D audio power amplifier ).

Analog or digital data such as transmitter power, temperature, VSWR, voltage, modulation level, and other status information are returned so that broadcast engineering staff can correct any problems as soon as possible.

Since Analog video recordings use frequency modulation for the luminance part ( composite video signal in direct colour systems ), which keeps the tape at saturation level, audio style noise reduction is unnecessary.

Analog information is still used up to a bandpass of about 7. 5kHz, with standard amplitude modulation.

Analog ( or analogue ) television is the analog transmission that involves the broadcasting of encoded analog audio and analog video signal: one in which the information to be transmitted, the brightness and colors of the points in the image and the sound waves of the audio signal are represented by continuous variations of some aspect of the signal ; its amplitude, frequency or phase.

) Analog color systems differ by the way in which infrequently used space in the frequency band of the signal is used.

Analog vocoders typically analyze an incoming signal by splitting the signal into a number of tuned frequency bands or ranges.

Analog signals that have not already been bandlimited must be passed through an anti-aliasing filter before conversion, to prevent the distortion that is caused by audio signals with frequencies higher than the Nyquist frequency, which is half of the system's sampling rate.

Analog audio's frequency response is less flat than digital, but it can vary in the electronics.

Analog ( or analogue ) recording ( Greek, ana is " according to " and logos " relationship ") is a technique used for the recording of analog signals which among many possibilities include audio frequency, analog audio and analog video information for later playback.

Analog Devices radio frequency ( RF ) RF ICs address the RF signal chain and simplify RF system development.

Analog A / V connectors often use shielded cables to inhibit radio frequency interference ( RFI ) and noise.

* Analog signal, a signal that contains information using non-quantized variances in frequency and amplitude:

The pair gain unit which performs the multiplexing can be as simple as providing two telephone connections over a single subscriber line ( called an Analog Multi-Line Carrier or AML ) in circumstances where a customer wants to add a new phone line for a fax machine or dial-up internet connection.

Analog Brothers is an experimental hip-hop crew featuring Ice Oscillator also known as Ice-T ( keyboards, drums, vocals ), Keith Korg also known as Kool Keith ( bass, strings, vocals ), Mark Moog also known as Marc Live ( drums, violyns and vocals ), Silver Synth also known as Black Silver ( synthesizer, lazar bell and vocals ), and Rex Roland also known as Pimp Rex ( keyboards, vocals, production ).

Analog television did not really begin as an industry until the development of the cathode-ray tube ( CRT ), which uses a steered electron beam to " write " lines of electrons across a phosphor coated surface.

Computer controlled music is also found in the performance pieces by the Canadian composer Udo Kasemets such as the Marce ( ntennia ) l Circus C ( ag ) elebrating Duchamp ( 1987 ), a realization of the Marcel Duchamp process piece Erratum Musical using an electric model train to collect a hopper-car of stones to be deposited on a drum wired to an Analog: Digital converter, mapping the stone impacts to a score display ( performed in Toronto by pianist Gordon Monahan during the 1987 Duchamp Centennial ), or his installations and performance works ( e. g. Spectrascapes ) based on his Geo ( sono ) scope ( 1986 ) 15x4-channel computer-controlled audio mixer.

Over the next five decades, he created covers for numerous books and magazines, notably Astounding Science Fiction both before and after its title change to Analog ; Mad magazine ( for whom he painted many early covers featuring the iconic character, Alfred E. Neuman ) from 1958 to 1962 ( he started at Mad in February 1957 and by July 1958 was the magazine's new cover artist ; he painted most of its covers until October 1962 ); cover art for DAW, Signet, Ballantine Books, Avon, all 58 Laser Books ( which are now collectors ' items ), and over 90 covers for Ace books alone.
