Because an analog signal takes up more bandwidth than the new digital format. By cutting off the analog signals and offering digital only, it frees up enough space on the network to offer services to a wider range of people. It also includes enhancements to the providers network. For example, faster internet speeds, more TV channels, and more features.
It is not 'necessary' in general, it is however necessary if you intend to use some digital equipment, which can only operate on digital signal directly, to use the analog signal.
While Digital Signal is useful in analyze, Analogue Signal is for transmission through different medium. For more info check the link.
When you convert digital signal to analog, it is called as an analog signal. The device used is called digital to analog converter.
An analog-to-digital converter is a device which converts an infinite resolution analog signal to a finite resolution digital signal.
transducer convert one energy to other energy .now in analog transducer it convert energy use of analog signal and digital it converts use og 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
First of all digital signal cant be transmitted wirelessly. digital signal can only be transmitted through optical fibre in the form of pulses. so we have to convert digital signal to analog form with the help of DIGITAL TO ANALOG CONVERTOR ( D TO A CONVERTOR). Then this analog signal should be super imposed on carrier signal called MODULATION. modem can be used for that. then that signal can be transmitted to the air through alloted band width like cellular system with the help of transceiver. at the reciveing end we can demodulate the signal with the help of modem & can convert it back to digital form through A TO D CONVERTOR.
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.
When you convert digital signal to analog, it is called as an analog signal. The device used is called digital to analog converter.
An analog-to-digital converter is a device which converts an infinite resolution analog signal to a finite resolution digital signal.
Because digital is in now
There is a device called a digital to analog converter (DAC).
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.
There are several devices called digital to analog converters for this purpose. 1s and 0s of the digital signal are used to represent the digital signal in analog form.
A UART does not convert an analog signal into a digital signal. It converts a serial digital signal into a parallel digital signal, and vice versa. The letters UART stand for Universal Asynchronous Receiver Transmitter. It is, fundamentally, a pair of shift registers.

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
There are four possible combinations of encoding techniques -Digital data, digital signal -Digital data, analog signal -Analog data, digital signal -Analog data, analog signal
