1. What is the distribution architectures?Transmitted terrestrially, via satellite, and through cable networks
2. How does an analog TV signal travel to my home?It can come from a big antenna on the roof (terrestrial), from a satellite in space (satellite TV), or through cables that run into the house (cable TV). Each method brings the waves to the TV.
3. Why does an analog picture sometimes look like snow or have wrong colors?Because the waves can pick up noise or interference while traveling. That noise changes the wave and makes the picture fuzzy, snowy, or color‑distorted.

Amplitude Modulation (AM): Varying the strength of a signal wave to carry information, often used for brightness.
Frequency Modulation (FM): Varying the rate of signal wave oscillations, used for audio and color.
