The _____ of a composite signal is the difference between the highest and the lowest frequencies contained in that signal.*1 pointChoose

The term you are looking for is "bandwidth." In the context of a composite signal, bandwidth refers to the difference between the highest frequency (f_high) and the lowest frequency (f_low) that the signal contains. It is a key concept in telecommunications and signal processing, as it determines the range of frequencies that can be used for transmitting the signal effectively.

More formally, Bandwidth can be represented mathematically as:

$\text{Bandwidth} = f_{high} - f_{low}$

In summary, the bandwidth of a composite signal is critical for understanding its transmission capabilities and limitations.
