Investigation Question: Create a table like the one below to demonstrate the similarities and differences between AM and FM radio waves. Use diagrams to demonstrate your understand also.
Investigation Question: Research how television signals are transmitted and use or draw a diagram to demonstrate your understanding.
Television signals have visual and audio carriers. The video is transmitted as an amplitude modulation (AM) signal and the sound as an frequency modulation (FM) signal. When watching television, both video and sound signals are both working at the same time. It removes the carrier waves now and replaces the sent signals into pictures and sounds.
