Answer #1

Solution:

SSB wave consists of either upper sideband or lower sideband.

carrier frequency fc =2.3MHz  

Intelligence signal or message signal frequency fm = 150 Hz to 4.2KHz

When  fm = 150 Hz:

Lower sideband frequency fLSB = fc - fm = 2.3M -150 =2.29985 MHz   

Upper sideband frequency fUSB = fc +fm = 2.3M +150 =2.30015 MHz

When  fm = 4.2KHz:

Lower sideband frequency fLSB = fc - fm = 2.3M -4.2k =2.2958 MHz   

Upper sideband frequency fUSB = fc +fm = 2.3M +4.2k =2.3042 MHz

Hence frequency range of the lower sideband  fLSB =  2.2958 MHz to  2.29985 MHz

  frequency range of the upper sideband  fUSB = 2.30015 MHz  to  2.3042 MHz

In GSM systems the signal direction from the mobile station to the network or the base station is referred to as uplink. Why are lower frequencies given to the uplink? A mobile network operator was allocated uplink frequency (890-915MHz) and downlink frequency (935-960MHz). Calculate the number of available RF channels for this operator and the duplex distance if the spectrum has a carrier separation of 100kHz. Why are Telco’s more interested in Radio channels?
