(a) A high frequency carrier signal with frequency of 8MHz is amplitude modulated by IMHz low frequency modulating signal. The AM signal is then applied to 12012. By using the oscilloscope, an AM signal shows the maximum and minimum amplitude of modulated signal as 41 V and 21 V respectively, determine i. Information signal voltage and carrier signal voltage. ii. Sideband power and total power of the signal. lii. The trigonometric equation of the above signal. iv. Sketch the AM signal. (10 marks)
