Why does a digital tuner for HDTV have a analog to digital converter?
The digital tuner also demodulates the normal analog broadcasting. The tuner outputs a analog composite video signal to Video Processing Chip. In that chip, there is a ADC to convert the analog to digital, then after procession, display the content on the screen
What is the expansion of Digital Signal Processing?
Digital Signal Processing
Why doesn't a digital TV with a digital tuner get a digital picture?
The signal sent to the TV must be a digital signal as well.
What is difference between digital image processing and digital signal processing?
Digital Image Processing is a type of Digital manipulation pertaining to pictures and video. "Photoshopping" a digital picture is an example of Digital Image Processing. Another example is what takes place in a digital camera when the image is captured on the image sensor and converted into a JPEG file to be saved on a memory card. Digital Signal Processing is a generic term for any manipulation of a Digitally encoded signal, such as Audio, Video, or Radio Signals. This also includes Digital Image Processing where there is a signal being sent from one part of a system to another, such as in a digital camera. There are Microprocessors that are specifically built to process digital signals known as "Digital Signal Processors" (or DSP's).
Which device is used to convert digital signals to analog signals or analog signals to digital signals?
The set top box that your provider gives you is what converts the Digital signal to the analog signal. The digital signal is compressed at the provider and sent to the end user. The "tuner" (which can be built into a tv, a set top box or a cable card) Then decompresses the digital signal and converts it into an analog signal. There is much more to this did not know how technical you wanted your answer.
Where is digital signal found?
Digital signals are found in various applications, including telecommunications, computer networks, and digital audio/video systems. They are used in devices such as smartphones, computers, and digital cameras, where information is represented in discrete binary values (0s and 1s). Additionally, digital signals are prevalent in broadcasting, data storage, and digital media streaming, enabling efficient transmission and processing of information.
What is the basic principle of digital television?
Digital television is simply the process of broadcasting a digital signal, instead of an analog one. This results in better sound and picture quality, as well as increased coverage.
Describe how a network based VoIP provider interacts with the PSTN?
PSTN will convert the digital signal from VoIP into voice signal. Their networks interacts using satellite frequency.
What is Broadcasting signal frequency range?
The broadcasting frequency range is from 300kHZ to 3400kHZ.

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.
Are digital converters necessary for every home?
The only time you will be in need of a digital converter is if you currently own an analog television that is connected to an over-the-air antenna signal.
Explain the characteristics of a digital signal?
what are the characters of digital signal
Is flame detector an analog or digital signal?
digital signal
What is the expansion of Digital Signal Processing?
Digital Signal Processing
What is included in a cell phone to handle the compression of data for it to be transmitted to another phone?
digital signal processor
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.
