A: The device is an IC chip called DAC for figital to analogue converter. they comes with many configuration of bits output.
No, it is an output device. It outputs sound waves.
modem is the device that carries digital signals
An individual square of a charge coupled device is analogous to a pixel in a digital image sensor. Each square, or pixel, in a CCD is responsible for detecting and converting incoming light into electrical signals, much like how pixels capture and display visual information in digital images.
An Electronic Device
A digitizer graph can be used to convert analog signals into digital signals by sampling the analog signal at regular intervals and assigning numerical values to the sampled points. These numerical values represent the amplitude of the signal at each sampled point, allowing the analog signal to be represented in a digital format that can be processed and stored by a computer or other digital device.
You would utilize a VoIP adapter in the conversion of analog voice signals into digital IP packets. These adapters also have the ability to convert digital IP packets into analog voice streams.
ADC analog digital converter
The set top box that your provider gives you is what converts the Digital signal to the analog signal. The digital signal is compressed at the provider and sent to the end user. The "tuner" (which can be built into a tv, a set top box or a cable card) Then decompresses the digital signal and converts it into an analog signal. There is much more to this did not know how technical you wanted your answer.
d. Modem It modulates digital signals to analogue signals and demodulates analogue signals back to digital signals.

When you convert digital signal to analog, it is called as an analog signal. The device used is called digital to analog converter.
