  • Digital Data Digital Signal
    Digital Data Digital Signal Digital signals are transmitted using LINE CODING technique Q: What is Line Coding? In telecommunication, a line code (also called digital baseband modulation, also called digital baseband transmission method) is a code chosen for use within a communications system for baseband transmission purposes. Line coding is often used for digital data transport. Q: What are the requirements of a Good Line Encoding Schemes A Desirable Properties for Line Codes are 1. Transmission Bandwidth: as small as possible 2. Power Efficiency: As small as possible for given BW and 3. probability of error 4. Error Detection and Correction capability: Ex: Bipolar 5. Favorable power spectral density: dc=0 6. Adequate timing content: Extract timing from pulses 7. Avoid Long strings of same pulse We can divide line coding schemes into three broad categories 1. Unipolar 2. Polar 3. Bipolar Ahmad Bilal swedishchap.weebly.com 1. Unipolar Unipolar encoding has 2 voltage states, with one of the states being 0 volts. Since Unipolar line encoding has one of its states at 0 Volts, it is also called Return to Zero (RTZ). A common example of unipolar line encoding is the TTL logic levels used in computers and digital logic. 2. Polar Polar encoding uses two voltage levels, one positive and one negative. Example NRZI 3. Bi-Polar Bipolar encoding, like Rz uses three voltage levels ; positive, negative and zero Schemes Polar Return to Zero Return-to-zero describes a line code used in telecommunications signals in which the signal drops (returns) to zero between each pulse. This takes place even if a number of consecutive 0's or 1's occur in the signal.

    White Paper: Virtex-5, Virtex-4, Spartan-3, LogiCORE R WP270 (v1.0.1) April 21, 2008 Forward Error Correction in Digital Television Broadcast Systems By: Michael Francis and Robert Green Digital television (DTV) broadcasting is in the process of migrating from analog to digital systems, with regions around the world at different stages of adoption. With some governments looking to auction off the remaining analog spectrum, deadlines have been set for regions to switch off analog TV transmission, resulting in growing demand for flexible technologies to enable a smooth transition in the timescales available. Various delivery systems are available for digital TV, but the main ones are satellite, cable, terrestrial, and mobile. Each has a variety of standards and derivatives that are either mature or emerging. These standards aim to ensure interoperability between different vendor’s equipment, including the set-top boxes, cell phones, and other means for DTV reception. Each region has their own requirements for a DTV delivery system, dependent on many factors, such as bandwidth available in the digital spectrum, the © 2007-2008 Xilinx, Inc. All rights reserved.
