basebandcommunicatie

Baseband communication is a method of transmitting signals where the signal is sent directly over the communication channel without modulation. This means the signal occupies the entire bandwidth of the channel. In baseband transmission, the information signal is used to directly modulate the carrier wave, or in some cases, no carrier wave is used at all. This is often seen in wired communication systems like Ethernet. The term "baseband" refers to the original frequency range of the signal, before any frequency shifting or modulation takes place. The signal is transmitted at its original frequencies. This contrasts with broadband communication, where the signal is modulated onto a higher frequency carrier wave, allowing multiple signals to share the same transmission medium simultaneously. Baseband signals are typically digital or analog. For digital signals, this involves sending pulses representing binary ones and zeros. For analog signals, the amplitude, frequency, or phase of the transmitted signal directly represents the information. The simplicity of baseband transmission means it is often more cost-effective for shorter distances and dedicated channels. However, it is susceptible to noise and interference, especially over longer distances.
