QUESTION 1

a) Calculate the percentage power saving when the carrier and one of the sidebands are suppressed in an AM wave modulated to a depth of 100 %.

b) The total power content of an AM signal is 1000 W. Determine the power being transmitted at the carrier frequency and at each of the sidebands when the percent modulation is 100%.

QUESTION 2

The FM wave voltage equation is represented as:

v = 12sin (6 * 108t + 5sin 1250t)

Find the:

i) carrier and modulating frequencies

ii) modulation index

iii) maximum deviation

iv) value of power this FM wave will dissipate in a 10W resistor
