The way that digital video and audio signals are handled, processed and transmitted allows delays to be added at almost every stage of the signal chain. The delays are of unspecified and changing duration. This isn't a problem as long as audio, video and other time sensitive data are kept as part of the same signal. When the audio is removed from the video signal, delays in either video or audio can become noticeable and disturbing.
It is possible that any of the audio outputs of the television can lead or trail the video signal. In most cases, the television will make adjustments internally to ensure that both are synchronized but this isn't always the case. If a discrepancy is noticed, it is worth taking a look in the set up menus to find settings that can adjust the delay. If no setting is available, this may just be a feature of the model. It is often worth a call to technical support for the television as there can be a variety of causes and solutions to the problem.
For the same reason that new TVs no longer use analog video signals. Everything is switching to digital.
The big difference is inputs and outputs. Digital ICs expect high/low true/false inputs and outputs. Analog ICs take any inputs, and produce outputs of any level. For example, an audio amplifier is an analog IC. It takes an analog input (sound), and produces an analog output (louder sound). A ripple counter is an example of a digital IC. It takes a digital input (clock pulses), and produces a number of digital outputs (the digital outputs of the flip flops, collectively representing a number in binary).
The number & types of inputs & outputs will vary with the complexity of the VFD & serve as a means of comparison between manufacturers of variable frequency drives. VFD inputs & outputs are either digital or analog signals. Digital inputs & outputs have two states (either on or off), while analog inputs & outputs have many states that vary across a range of values.
Yes, as long as your computer is equipped with an analog headphone or speaker jack (most are).
5.1 analog outputs; 7.1 is only for the digital output only
It's a device that samples an analog signal and outputs an equivalent binary value
You would have to purchase a Digital to Analog converter and connect the SPDIF (orange RCA connector) to the D/A converter's digital input via a RCA/SPDIF cable. Then you would have to connect some type of headphone amplifier to the line outputs of the D/A converter.
Digital sensors produce digital output (0 or 1) which can be easy to communicate directly with a microcontroller. Analog sensors provide analog outputs which one must firstly digitize to sense the level. Analog sensors are generally more accurate.
yes
You will need a sound card with a digital output (coaxial or optical) or a sound card with surround audio outputs and a receiver with 5.1 analog inputs to make it work.
According to http://www.answers.com/optical+drives, David Paul Gregg developed an analog optical disc for recording video and patented it in 1961 and 1969.
You can get an optical to coxial converter box if your receiver has a coaxial digital input. If it doesn't, you will have to purchase an optical digital to analog (D to A) converter.
