North American broadcast television frequencies
Okay kiddo, so you know how you can turn on the TV and watch all sorts of shows and movies? Well, those shows and movies come through something called broadcast television frequencies.
Think of it like this - when you want to talk to your friend who's far away, you need to pick up the phone and call them, right? Well, when you want to watch something on TV, your TV picks up a signal that's being sent out over the airwaves. This signal is made up of different frequencies that your TV can pick up and turn into a picture and sound.
In North America, there are different frequencies that are used for broadcast television. These frequencies are divided into different bands, kind of like different groups of channels.
The most commonly used broadcast television frequency bands in North America are VHF (very high frequency) and UHF (ultra high frequency). These bands are divided up into different channels which are assigned to different TV stations.
Each channel has a specific frequency that it uses to broadcast its signal. For example, Channel 2 might use a frequency of 54-60 MHz (that's millions of hertz - a measure of frequency), while Channel 7 might use a frequency of 174-180 MHz.
So, when you tune your TV to a certain channel, it's actually picking up the frequency that's being used to broadcast that station's signal. And different stations use different frequencies to avoid interfering with each other.
That's the basics of North American broadcast television frequencies, kiddo. It's kind of like phone calls, but instead of talking to your friend, your TV is picking up signals from different channels that are using specific frequencies to send out their shows and movies.
