We use different forms of electromagnetic radiation to function lots of forms of technology. For example, Radio waves and Microwaves are commonly used for wireless tech because of their low frequencies which create a much longer range.
But how exactly are 1’s and 0’s put into them?
In: Engineering
There are different methods. The standard on and off is one method. There’s also frequency shift keying where a carrier wave on the signal will shift frequencies carrying data of a one or zero based on the frequency of the carrier wave being sent. So, there would be the standard sine wave of the signal and then it would have what would look like noise along the wave, but is actually a specific frequency indicative of a 1 or 0.
