Because digital signals do not depend on amplitude or frequency differences to communicate information, they are more vulnerable to emi noise.

False

Electromagnetic interference happens less commonly with digital signals because they do not rely on subtle amplitude (signal strength) or frequency differences(cycles in a certain time) to communicate information. Digital signals are readable even with distortion generated from electromagnetic interference noise

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.
