There devices called A/D oranalog to digital. where by a ref is setup and is basically compared to their input as more-less value. bits of data or 1-0 are output out to represent the analog input as digital bits . For a designer there are errors to be considered . resolution basally how much an lsb is worth in voltage. quantization uncertainty ,linearity errors offset errors full scale errors for gain control, monotonicity and finally conversion timing. lsb IS LEAST SIGNIFICANT BIT NOT POUNDS.
by rectifiers we can able to change from ac to dc
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
The only way is to digitize the audio signal and send it as data
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.
it means that you digitize analog data for transmission . Like 2 computer that chatting .
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.

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
The input to the earphones is a a analog signal i.e., electrically generated analog signal.
An analog signal is a continuous signal that contains time-varying quantities. Unlike a digital signal, which has a discrete value at each sampling point, an analog signal has constant fluctuations. netonplus.com

where an analog signal is to be converted into digital signal,because in some applications we need digital signal where we have analog signal that is we use an A/D converter
