All communications systems are constrained by_____________.
A)bandwidth availability
B)reference frequency
C)sound waves
D)absence of modulation

Question

Quizplus · Accepted Answer

Bandwidth availability refers to the limited amount of frequency spectrum available for communication systems. All communication technologies must work within this constraint to avoid interference and provide reliable services. Therefore, option A is the correct choice for this question. The reference frequency, sound waves, and absence of modulation do not necessarily constrain communication systems in the same way.
