Q1. Create a table like the one below to demonstrate the similarities and differences between AM and FM radio waves. Use diagrams to represent your understandings also
Q2. Research how TV signals are transmitted and use or draw a diagram to demonstrate your understanding also.
TV signals are transmitted on two separate carrier waves, a visual signal and audio signal. The visual signal is added onto a carrier wave using amplitude modulation (AM). The audio signal uses frequency modulation (FM). When you tune your television to a channel of your choice you are selecting a visual and audio carrier waves that you wish to receive. Your television set completes the task of removing the carrier waves and then translating the signals onto the television screen to a picture and and also sound.
