There are chips that will convert a analog to a digital form. It works on the principle of comparing the input to a reference voltage and outputting the bits [digital] as a value compared to the reference voltage. it can be 4,8,12, of digital data for a 12bits the LSB is 2.4mv.
An Analog to Digital Converter (ADC) takes an analog input signal and converts the input, through a mathematical function, into a digital output signal. While there are many ways of implementing an ADC, there are three conceptual steps that occur.
Sound is commonly translated into an analogue signal using a microphone. This is achieved with the help of the two electrically charged plates that sound has.Ê
If I were you, I would try and use a so called 'Digital-Analog Converter' or shortly D/A converter.

When you convert digital signal to analog, it is called as an analog signal. The device used is called digital to analog converter.
Digital signal processing is the best compared to analog signal. It is because the digital signal is moreefficienterror freeimmune to noisethan an analog signal
It isn't always. Baseband analog signals have no carrier.
An analog-to-digital converter is a device which converts an infinite resolution analog signal to a finite resolution digital signal.
while conversion of analog signal to digital signal, we need to convert continuous analog signal to discrete signal. this can be done by dividing the analog signal into specific time slots. this process is known as sampling. there is a condition for sampling that can be given as follows. fs<=2fm
Analog-to-digital conversion
DSP -Digital signal processing the word it self says it is process of analyzing the digital signal . The system which does this work of analysis is the digital signal processing system. In this system the raw analog signal(ex:human voice) which is time domain signal is fed to the pre aliasing filter which removes noise part of the signal and this fed to the sampling and quantization in which the real time analog signal is discretized and digitized . After this process this digitized signal is fed to the DSP processor to do the specific operation on the signal (ex: convolution , modulation etc.,) .This processed signal is fed to the D/A which converts the digital signal to the analog signal real time signal. after all explaining the process of signal processing. the stages between the sampling and D/A is the digital processing system.
Naturally occurring sound waves are analog, although they can be digitized.
A digital signal is a physical signal that is a representation of a sequence of discrete values (a quantified discrete-time signal), for example of an arbitrary bit stream, or of a digitized (sampled and analog-to-digital converted) analog signal. The term digital signal can refer to either of the following:any continuous-time waveform signal used in digital communication, representing a bit stream or other sequence of discrete valuesa pulse train signal that switches between a discrete number of voltage levels or levels of light intensity, also known as a line coded signal or baseband transmission, for example a signal found in digital electronics or in serial communications, or a pulse code modulation (PCM) representation of a digitized analog signal.A signal that is generated by means of a digital modulation method (digital passband transmission), to be transferred between modems, is in the first case considered as a digital signal, and in the second case as converted to an analog signal.
If you mean the IP phone system. This is a system that uses the Internet connection to transfer the analog or voice signal. It does not use the traditional phone line. The voice signal is digitized in the form of packets, gateways are use to do the conversion.
Analog Modulation
An DAC convert digital signal to analog signal i.e Digital to Analog Converter. An ADC convert analog signal to digital signal i.e Analog to Digital Converter.
The theoretical minimum sampling rate required in order to avoid frequency aliasing is 3.4 KHz.
When you convert digital signal to analog, it is called as an analog signal. The device used is called digital to analog converter.
Digital signal processing is the best compared to analog signal. It is because the digital signal is moreefficienterror freeimmune to noisethan an analog signal
There are four possible combinations of encoding techniques -Digital data, digital signal -Digital data, analog signal -Analog data, digital signal -Analog data, analog signal
A video uses the analog signal
