Question 4 A communication satellite transmits data using radio waves. The received signal often experiences attenuation and distortion due to atmospheric effects. a) Distinguish between amplitude modulation (AM) and frequency modulation (FM) used in radio wave communication. (2 marks) b) For a digital data transmission, explain why FM might be preferred over AM when dealing with signal attenuation. (2 marks) Answer a) Amplitude modulation (AM) and frequency modulation (FM) are two types of modulation techniques used in radio wave communication. Both of them involve changing certain characteristics of a carrier wave in order to transmit information. AM is a type of modulation where the amplitude of the carrier wave is varied in order to carry the audio signal. This means that the amplitude of the carrier wave increases and decreases in proportion to the amplitude of the audio signal. The frequency and phase of the carrier wave remain constant. On the other hand, FM is a type of modulation where the frequency of the carrier wave is varied in order to carry the audio signal. This means that the frequency of the carrier wave changes in proportion to the amplitude of the audio signal. The amplitude and phase of the carrier wave remain constant. b) FM is generally preferred over AM for digital data transmission when dealing with signal attenuation. This is because FM has a wider bandwidth compared to AM, meaning it can carry a larger range of frequencies. This makes FM less susceptible to signal distortion and attenuations due to atmospheric effects. In digital data transmission, the information is represented by distinct digital symbols, rather than analog signals like in AM and FM. These symbols can be represented by a combination of different frequencies. FM's wider bandwidth allows for a greater number of frequencies to be used, making it better suited for transmitting digital data. Additionally, FM has a better signal-to-noise ratio compared to AM, which helps in reducing errors in data transmission. This is important for digital data, as even a small amount of distortion or noise can result in significant errors in the transmitted data.
