\"Radio waves\" transmit music, conversations, pictures and data invisibly through the air, often over millions of miles -- it happens every day in thousands of different ways! Even though radio waves are invisible and completely undetectable to humans, they have totally changed society. Whether we are talking about a cell phone, a baby monitor, a ...
The list goes on and on... Even things like radar and microwave ovens depend on radio waves. Things like communication and navigation satellites would be impossible without radio waves, as would modern aviation -- an airplane depends on a dozen different radio systems. The current trend toward wireless Internet access uses radio as well, and that m...
The funny thing is that, at its core, radio is an incredibly simple technology. With just a couple of electronic components that cost at most a dollar or two, you can build simple radio transmitters and receivers. The story of how something so simple has become a bedrock technology of the modern world is fascinating!
- Broadcasting. Main page: Broadcasting. AM radio station. FM radio station. Television station. Broadcasting antennas. Broadcasting is the one-way transmission of information from a radio transmitter to receivers belonging to a public audience.
- Jamming. Radio jamming is the deliberate radiation of radio signals designed to interfere with reception of other radio signals. Since radio waves can pass beyond national borders, some totalitarian countries which practice censorship use jamming to prevent their citizens from listening to broadcasts from radio stations in other countries.
- Two way voice communication. (left) Modern cellphone. (right) Cellular phone tower shared by antennas belonging to 3 different networks. A two-way radio is an audio transceiver, a receiver and transmitter in the same device, used for bidirectional person-to-person voice communication with other users with similar radios.
- One way voice communication. One way, unidirectional radio transmission is called simplex. Baby monitor – this is a cribside appliance for mothers of infants that transmits the baby's sounds to a receiver carried by the mother, so she can monitor the baby while she is in other parts of the house.
Millions of radio waves--carrying sound wave signals and digital signals--reach your receiver every second. The receiver's tuner picks out a specific signal. Its amplifier strengthens that signal. A demodulator separates the signal from the carrier wave. And then a speaker converts the signal to the sound waves that you hear!

Mar 8, 2022 · The video explains. how a simple radio receiver works to receive the signal, extract the sound information, and amplify it so that it can be heard. Part 2 explains the development of radio technologies from amplitude modulation (AM) to frequency modulation (FM). A major part of Pye’s business in the 20th century was built on radio technology.
