Question

Hi all: Why is it that we have a dozen or so different electromagnetic wave types and yet every one of them can be used for analog and digital communication?

Thanks!

Answer 1

Essentially, the different types of electromagnetic waves vary in frequency and wavelength which allows for different applications and efficiencies in communication. However, the fundamental principles of encoding and decoding information can be applied to any type of wave, whether analog or digital.
