a. Explain in detail the essential things that happen to the modulating signal before transmission. Discuss all types or kinds available if necessary. Note that without these essential systems, transmission will not be able to be sent to yield the needed result. In an AM transmission system the transmitter current was found to be b. 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%. c. If the amplitude of the modulation signal voltage was given to be -4v and +4v and carrier amplitude also given to be -22v and +22v, by suitable waveform diagram determine the Am modulated output. Remember to provide all necessary wave forms in practical terms.
