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.
Does a digital camera use digital signals?
The signal directly from the sensor is analog. It is than converted to digital, and a digital signal is used for processing. The signal directly from the sensor is analog. It is than converted to digital, and a digital signal is used for processing.
What is the use of demultiplaxer in digital electronics?
Demultiplexers are used in digital electronics to get a signal at the input and produce so many at the output.
What type sensors produce a digital signal?
A simple on-off witch gives a digital signal. And the temperature / time sensor in my toaster. But most sensors and transducers actually produce an analog signal, which is then digitally conditioned. This conditioning is done because modern techniques allow quite large resolution (256 - bit resolution or better for example) to be developed. And one notable advantage of digital signal processing is that signal noise is largely eliminated.
How does a digital camera create the electrical signal?
at first it will be you taking a picture and after when you push the button a spark lights to make a wire activate which sends the signal
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.
What is going on with my cable my audio is interrupted,digital picture signal goes haywire,picture freezes,I thought digital was better,not.This happens for no apparent reason. My daughter has satelite and none of these problems. TW customer for 30yrs. ?
either the signal is bad or the channel is experiencing technical difficulties.
Difference between analog video and digital video?
analog video is generally a type of video form in which we have numerous waves in terms of crests and troughs in a continuous manner upside-down on X axis whereas, in digital video we have many bars that are upawrds and then downwards on X axis in a continuous manner that also includes two types of binary bits, either 0 or 1.
Why are some converter boxes some cheap some expensive?
A Digital Television (DTV) Converter Box is an electronic device that converts the new free over-the-air digital signal into an analog signal viewable on older "analog" television set. The digital to analog converter box connects your antenna or rabbit ears to your TV set. It will allow you to continue watching TV after February 17, 2009, the day the transition to "all digital" takes place. A digital to analog converter box will not give you a digital picture on an analog TV set. Analog TV sets using the set top boxes will show digital broadcasts, but not in the full picture quality of digital TV. However, your picture will be better than it was with the old analog signal. Technically speaking about picture quality: The reason the picture quality won't be as good on an analog TV set is because of the display resolution. Analog TV screens aren't designed to display the same level of picture quality and resolution that is found in the digital TV signal.
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.
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).
Explain the characteristics of a digital signal?
what are the characters of digital signal
