CCI Registered Cardiac Sonographer - Exam Topics Sample Questions

A signal that is increasing in strength would be considered a ________ decibel?

Correct Answer:
positive


the term "decibel" is commonly used in the fields of acoustics, electronics, and communications to quantify the level of a signal, such as sound or electromagnetic waves. named after alexander graham bell, the decibel (db) is a logarithmic unit that expresses the ratio of two values of a physical quantity, often power or intensity.

when discussing signals, whether they are audio signals, radio signals, or any form of electromagnetic wave, the strength or power of the signal is often measured in decibels. the decibel scale is relative and expresses gains or losses in power. it indicates the level of change from one state to another and is calculated using the logarithm of the ratio of these two power levels.

when a signal's strength increases, this change is described as a positive decibel change. this is because the logarithmic calculation used to determine the number of decibels results in a positive value when the final power is greater than the initial power. a positive db value indicates that the signal has grown stronger compared to its original level.

conversely, if a signal is decreasing in strength, this change is described as a negative decibel change. in this case, the logarithmic calculation results in a negative value because the final power is less than the initial power. a negative db value thus indicates that the signal has weakened.

therefore, when a signal is increasing in strength, it would be considered a "positive decibel." this indicates an increase in the power or intensity of the signal, signaling an amplification or gain in its strength. understanding these concepts is crucial in fields such as audio engineering, broadcasting, and telecommunications, where managing signal levels is essential for effective communication and sound reproduction.
