Difference between the highest and lowest frequencies of a signal is the definition of which of the following terms?

The term that defines the difference between the highest and lowest frequencies of a signal is bandwidth. Bandwidth is a crucial concept in both telecommunications and electronic warfare, as it determines the range of frequencies that a signal can occupy. A higher bandwidth allows for more data transmission and greater signal clarity, while a lower bandwidth can limit the amount of information transmitted and impact the performance of communication systems.

In the context of electronic warfare, understanding bandwidth is essential for effective signal analysis and counter-measures, as it directly relates to the capability of detecting, intercepting, and jamming hostile signals. Bandwidth can influence how systems are designed to operate within certain frequency ranges, making it a foundational concept for those involved in electronic warfare practices.
