  1. what is the relationship between data rate and bandwidth Soher almursheidi 120080089

  2. what is the data rate Amount of information that can be transferred per unit time, for example bits per second (bps). Technically, data rate is the correct term for what is often referred to as bandwidth for networks. what is the bandwidth computer networking and computer science, bandwidth, digital bandwidth, or network bandwidth is a measure of available or consumed data communication resources expressed in bit/s or multiples of it (Kbit/s, Mbit /s etc)..

  3. for high data rate ( data transfer speed ) the bandwidth of the signal carrying system should be high. because a high data rate means a high frequency ( square ) wave actually such a wave consists of a large number of waves having a range of frequencies Fourier analysis) so to get a distortion less transmission the bandwidth should be high

  4. WHY BANDWIDTH EFFICIENT MODULATIONS? • ACCOMMODATE MORE USERS AND HIGHER DATA RATES GIVEN A FIXED FREQUENCY RESOURCE • AVOID INTERFERENCE TO ADJACENT FREQUENCY BANDS (PARTICULARLY THE DEEP SPACE BANDS) • REDUCE BURDEN OF FREQUENCY COORDINATION • FCC MAY AUCTION AWAY PARTS OF SPACE FREQUENCY ALLOCATION IF IT DECIDES SPACE AGENCIES ARE NOT MAKING EFFICIENT USE OF THE SPECTRUM
