unreferenced date August 2008 Analogvideo is a video signal transferred by analog signal . A color video signal usually contains the luminance brightness and chrominance color of the image, which may be carried in separate channels, as in component video YPbPr and S Video , or combined in one channel, as in composite video and RF connector . Analogvideo is used in both consumer and professional applications. However, digital signal formats with higher quality have been adopted, including serial digital interface SDI , Firewire IEEE1394 , Digital Visual Interface DVI and High Definition Multimedia Interface HDMI .

Analog sequencers were the first generation of music sequencer s. Their peculiarities and limitations left a lasting stylistic imprint on Berlin School of electronic music Berlin School electronic music , and hence, indirectly, in many later rhythmic synthesizer driven music genres such as techno , trance music , 1980s synth pop , house music house , ... At its most basic, an analog sequencer is nothing but a bank of potentiometers and a clock that steps through these potentiometers one at a time and then cycles back to the beginning. The output of the sequencer is fed as a control voltage and gate pulse to a synthesizer. By tuning the potentiometers, a short repetitive rhythmic motif or riff can be set up. The most commonly used analog sequencer was the Moog 960, which was a module of the Moog modular synthesizer . It basically consisted of three parallel banks of eight potentiometers the three banks could either steer three different Voltage controlled oscillator VCO s to allow three note chords in the sequence, or for example one row could steer pitch while the second row is patched through to the filter cutoff or VCA volume, and a third steers filter cutoff for a white noise generator thus creating an extremely primitive electronic drum track . Under each of the eight steps, a switch offered three options play this step, skip this step, or loop back to the beginning.

In a film camera using the gelatin silver process , light falling upon photographic emulsion s containing silver halide s is recorded as a latent image . The latent image is subjected to photographic processing , which makes it visible and insensitive to light. In a video camera or digital camera digital still camera , the signal is captured with a video camera tube or charge coupled device sensor, which sends the picture to be processed by the camera s electronics. The signal can be transmitted or recorded on a Storage media Recording medium storage device for later playback.

It can differ in one or more atom s, functional group s, or substructures, which are replaced with other atoms, groups, or substructures.

Analog forestry is a system of planned, managed forests, primarily employed in tropical or subtropical areas. The forests are designed to mimic the function and ecology of the preexisting climax vegetation for the area, and are also designed to provide economic benefits. Analog forestry draws design input not only from traditional models but also from the natural forest successional dynamics. When an ecosystem is designed to be analogous to the indigenous climax state, the efficiency and dynamics of the natural processes can be replicated. These quasi natural forests are designed to mimic the structural and functional aspects of indigenous forests and are referred to as analog forests. In addition to their ecological characteristics, analog forests are also designed to provide economic benefits. However, it is not until all the ecological requirements of the location are satisfied that economic values of species are considered. Therefore, an analog forest may comprise natural and exotic species in any proportion, the contribution to structure and function being the overriding factor that determines its use. It arose in Sri Lanka around 1981 as an alternative to monocultures of Pinus and Eucalyptus and has spread to India , Vietnam , Philippines , Australia , Peru , Ecuador , Colombia , Brazil , Costa Rica , Dominican Republic , Honduras , Mexico , Canada , Kenya and Zimbabwe at present.

Decline of the analog multiplier In most cases the functions performed by an analog multiplier may be performed better and at lower cost using Digital Signal ... digital solutions increases much more steeply than for analog solutions. As digital technology advances, the use of analog multipliers tends to be ever more marginalised towards higher frequency circuits ... more details
An analog chip is a set of miniature electronic analog circuit s formed on a single piece of semiconductor material. Description The voltage and Electric current current at specified points in the circuits of an analog chips vary continuously in time. In contrast, digital chips only use and create voltages or currents at discrete levels, with no intermediate values. Analog chips often have much more passive elements Inductor Capacitor s Resistor s than digital chips. Analog chips may also contain digital logic elements to replace some analog functions, or to allow the chip to communicate with a microprocessor . For this reason and since logic is commonly implemented using CMOS technology, these chips use BiCMOS processes by companies such as Freescale , Texas Instruments , STMicroelectronics and others. This is known as mixed signal processing and allows a designer to incorporate more functions in the chip. Some of the benefits include load protection, reduced pats count and higher reliability. ref Information Freescale website, Mar 28th 2010, http www.freescale.com webapp sps site overview.jsp?nodeId 014359sMjvtxRl&tid taDR About Freescale Analog Products ref Pure analog chips in information processing have been mostly replaced with digital chips. Analog chips are still required for wideband signals on account of sampling rate requirements, high power applications and at the Transducer ... examples of long lived and well known analog chips are the Operational amplifier 741 Operational Amplifier , and the 555 timer IC 555 timer . Power supply chips are also considered to be analog chips ... elements of those systems.
