Question 1(TCO 4) From the spectrum analyzer display shown below, determine the total bandwidth needed to transmit that signal.10KHz20KHz30KHz60KHz Question 2(TCO 4) From the spectrum analyzer display below, determine the modulation frequency.2KHz5KHz10KHz60KHz100KHz Question 3
(TCO 4) Using the Bessel chart below, determine how many significant sideband pairs a transmission with a modulation factor of 1.0 would generate.12357 The Bessel Function table shows three(J3) significant pairs of sidebands corresponding to a modulation factor of 1. Question 4(TCO 4) An FM transmitter has a carrier frequency of 160.25MHz, a deviation of +/-20KHz and audio modulation frequency of 5KHz. Calculate the modulation factor?24520160.25 Modulation factor is given by: Deviation in carrier frequency / Modulation frequency Modulation Factor = 20 KHz / 5 KHz = 4
