Fundamentals of Modulation and Baseband Signals

Free model

The problem with sending these raw baseband signals over long distances, especially wirelessly, is twofold:
1. Antenna size: To transmit low-frequency signals efficiently, antennas need to be very large (often many meters long), which isn't practical.
2. Interference: If everyone broadcasted their raw voice, all the signals would overlap in the same frequency range, causing massive interference.
