Baseband and Broadband
• Baseband: digital signals sent through direct current (DC) pulses applied to a wire
– Requires exclusive use of wire’s capacity
– Baseband systems can transmit one signal at a time
– Ethernet
• Broadband: signals modulated as radiofrequency (RF) analog waves that use different frequency ranges
- Does not encode information as digital pulses
