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).
Difference between square wave and digital signal?
A: square wave can be positive and or negative. A digital signal is a square wave but it can be of invariable duty cycles
What is the basic principle of digital television?

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.
Can anyone say you the diff between routing and broadcasting in wireless technology?
Routing was design to avoid broadcasting. It basically means that when you establish connection with remote computer you send messages only to the computer and nobody else. Broadcasting is opposite to routing, and it was design to explore networks around you. When you send a broadcast signal you send to everybody in the specified network.
