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.

What is it called when you convert a digital signal to analog?
When you convert digital signal to analog, it is called as an analog signal. The device used is called digital to analog converter.
What is convert analog to digital convert?
An analog-to-digital converter is a device which converts an infinite resolution analog signal to a finite resolution digital signal.
What are the differences between analog and digital transistors?
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
What is meant by sampling in analog to digital conversion?
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
How can you convert the digital signal given on the speedometer in the car into radio waves which can be received some where else?
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.
What converts a message from digital to analog and analog to digital?
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.
What is it called when you convert a digital signal to analog?
When you convert digital signal to analog, it is called as an analog signal. The device used is called digital to analog converter.
What is convert analog to digital convert?
An analog-to-digital converter is a device which converts an infinite resolution analog signal to a finite resolution digital signal.
Why is it necessary to convert a analog signal into a digital signal?
Because digital is in now
How CD players convert digital signal to and analog signal?
There is a device called a digital to analog converter (DAC).
What are basic elements of digital signal processing?
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.
How do you convert digital signal to analogue signal?
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.
How does a UART convert an analog signal to a digital signal?
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.
What are the differences between analog and digital transistors?
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
How can you convert the digital to analog or analog to digital?
Buy a new digital ready tv, get a digital receiver Sky or Freeview for your analogue tv
What is meant by sampling in analog to digital conversion?

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