It used to be an analogue process but now it could be either
analog device
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.
digital
Analogue to digital is a conversion process not a transmission process.
Analog signals, such as sound or light, are converted into digital form through a process called analog-to-digital conversion. This process involves quantizing the continuous analog signal into discrete, digital values represented by binary numbers. Once in digital form, the signal can be processed, stored, and transmitted more efficiently and accurately.
The basic elements in digital signal processing are an analog to digital converter, digital signal processor, and digital to analog converter. This process can take an analog input signal, convert it to digital for processing and offer an analog output.

Analog to digital conversion done by the ADC's. It's digitization. ... Also referred to as video capture.
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.
No. In the general case, a buffer amplifier is an analog device, but an AND or an OR gate is a digital device. Even in the specific case of a digital buffer amplifier, its still not the same because the digital buffer amplifier has more power available in its output circuit, giving it a higher fanout than just an ordinary AND or OR gate.
A digital signal requires a repeater, which retransmits the signal in its original form, and an analog signal requires an amplifier, which increases the strength of both the signal and the noise it has accumulated.
It is a signal checking or comparing ckt..... So we can use it in the analog or digital locker ckt's or in security check's etc....
