Analog to Digital (A/D) Converter Why do we need Analog to Digital converters? In the real world, most data is characterized by analog signals. In order to manipulate the data using a microprocessor, we need to convert the analog signals to the digital signals, so that the microprocessor will be able to read, understand and manipulate the data. How does an A/D Converter work? The main goal of
In the case of analog component input signals, A/D conversion is carried out on the basis of the CCIR (4 : 2 : 2) digital TV studio standard; i.e., the sampling frequency is 13.5 MHz for luminance component signals ( Y) and 6.75 MHz for two color difference components signals (CB, CR), and the quantization precision is 8-bit PCM. In the case of digital component input signals, on the other
In 1995, the terrestrial standard for the transmission of digital TV pro- grams was defined in ETS 300744 in connection with the DVB-T project. A DVB-T channel can have a bandwidth of 8, 7 or 6 MHz.

A signal is a description of how one parameter depends on another parameter. For example, the most common type of signal in analog electronics is a voltage that varies with time. Since both parameters can assume a continuous range of values, we will call this a continuous signal. In comparison, passing this signal through an analog-to-digital converter forces each of the two parameters to be

The hardware used for analog-to-digital conversion of video signals is called a frame grabber. This is usually in the form of an electronics card that plugs into a computer, and connects to a camera through a coaxial cable. Upon command from software, the frame grabber waits for the beginning of the next frame, as indicated by the vertical sync pulses. During the following two fields, each
