An analog input voltage (or current) would be sent to device called an analog-to-digital converter (ADC or A/D). It is then converted to a discrete number and either processed or stored. In practical terms, you would have a device that has audio input connector(s) and digital output connector(s).
Speakers are analog devices. There is no cable and connector that will connect a digital audio jack to a speaker without a digital to analog conversion and an amplifier. If the audio output is digital, you will need a compatible amplifier that has the same digital input. Then you will need to link the amplifier to the speaker with exterior grade cable.
It's not as simple as making a cable that fits. Digital audio cables and digital signals, both coaxial and optical, require a digital input. You need to convert the digital signal to analog to work with older receivers. These are available (Google Digital to Analog Converter or DA Converter). Just about every device that has a digital output will also have an analog stereo output, which will work with your old gear.
No, a S/PDIF is, by definition, a Sony / Phillips Digital Interconnect Format connector, and is always a digital signal. It is usually connected by an RCA cable, and can be carried by cable specified for analog use, but digital cable is better.
They are red and white, or red and black for analog audio. Digital cables can be any color, as can HDMI cables.
To have digital to audio played back it has to be changed back to analog with the use of a DAC or digital to analog converter. The DAC will take the digital signal and try to recreate it as a analog signal.
A digital audio jack serves the same purpose as an analog audio jack, only it transmits a signal that is digital (1s and 0s) instead of analog (waveform).
Yes, the microphone or line in -input converts your analog signal into digital.
Bluetooth is a digital communication interface. It tends to be used for audio signals more than other applications so it is often perceived as carrying analog audio. Despite the appearance, it is definitely digital and not analog.
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).
No. S/PDIF carries only compressed digital audio, although it sometimes uses analog connectors.
Analog Pulse modulation is discreet in time but the formation is transmitted in continuous form. In digital pulse modulation, not only the time axis is discreet but the information is also in digital form. Examples of Analog PM are PAM and PTM i.e pulse amplitude and pulse time modulations respectively. Examples of Digital PM are PCM and PDM i.e pulse code and pulse delta modulations respectively.

In an analog phone, the mechanical energy of sound (speech) is picked up by a microphone (mic) and converted into an (analog) electrical signal. This signal is then put through whatever electronics stages are required (if any) to get the signal onto a phone pair for transmission to the receiver. In a digital cell phone, the mic picks up the sound and converts that into an analog electrical signal. That analog signal is then sent to an electrical stage called an analog-to-digital (A to D) converter. Once the signal is digitized, it can be treated as a data string and amplified and broadcast (to the cell hub) as such. An incoming call is a digital data string that is D to A converted in the phone and then the newly recovered analog signal is made to be heard by the user. The difference between the two is the conversion and re-conversion (analog to digital and digital to analog) in the digital cell phone.
analog audioRefers to recording audio in a format of continuous vibrations that are analogous to the original sound waves. Before audio recording became digital, sounds were "carved" into vinyl records or written to tape as magnetic waveforms. Contrast with digital audio
There are speaker cables, unbalanced analog cables, balanced analog cables, coaxial digital audio cables and optical audio cables.
There isn't really a difference, rather, MP3 is a digital form of audio. Technically, an MP3 is the standard way of compressing of audio into smaller, more manageable digital files for the computer.
