I'm wondering about the sign of dBc. Is it a positive value or a negative one? I need to know this to understand how it's used in measurements.

dBc is a measurement unit that is referenced to the carrier amplitude.

This means that dBc compares the power of a signal to the power of the carrier wave.

The carrier wave is the main signal that carries information in a communication system.

When a signal is measured in dBc, it is expressed as a negative value.

This is because the signal's power is always less than the carrier's power.
