- 1 (AM) An AM transmitter has a 1KW carrier power and is modulated by a sinusoidal tone. If you have 0.7 modulation index, what is the total power necessary for transmission?In an AM transmission system the transmitter current was found to be 9.A. If the carrier signal is the only one to be sent and later increases to 10.72 A. Also if the carrier is modulated by a single sinusoidal wave, compute the percentage modulation. Again find the current of the antenna if the percentage of modulation changes 85%.Answer the following on a clean sheet of paper. Take a photo of your answer sheet then upload here. Assuming that an oscilloscope displays a Vmax of 5.22V and Vmin of 1.33V. Calculate the percentage of modulation. (5 points) Three (3) AM broadcast stations are spaced at 18 kHz, beginning at 73 kHz. Each station is allowed to transmit modulating up to 6 kHz. Compute for the upper and lower sidebands of each station and plot it in the frequency domain. (15 points) Given a Vmax of 7.45V and a modulation index of 0.691, calculate for Vmin. (5 points) A station is given a carrier frequency of 88 kHz. Having a modulating frequency of 12 kHz, compute for the upper and lower sidebands of the station. (5 points)
