Your TV doesn't speak English, it speaks frequency
As part of our requirement in General Chemistry 2 and General Biology 2, we went to an exhibit led by college students in MB Hall and MB 6th Floor. The exhibitor of the model was Julius Osio Lumbera who was able to replicate on how signals are being transmitted from commercial broadcasting network into our own homes with the help of our antenna. A broadcasting network will spread signals in form of frequency and then be received by stirrer that rotates to vary direction and polarization sign als. Once turned on, you can see the sustained frequency circling the screen. When he started to make a call, a sudden interference in the signal occurred because of the p rincipal operating frequency of cellphones ranges from 700 to 800 MHz, strong enough to interrupt our signals in television. He also gave us a trivia about frequency and said that Smart is better than Globe because it gives off lower frequency signals better for penetration in solids like walls. With his exhibit, I was able to understand more about on how frequency travels from broadcasting network up to our homes.
