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
In real life there are no 1’s and 0’s. There’s just varying levels of things.
To put 1’s and 0’s on something you have to define what it means to do that. So we say, “if the wind is strong that’s a 1. If it’s not windy it’s a 0.”
If it’s somewhere in the middle we throw a flag and start checking parity bits and whatever other error correction we have in hopes we can figure out what was meant to be said. If that doesn’t work or is impossible to resolve then we blame the source for the error, because they need to send clearer signals.
