Signal Processing

What makes the invisible, visible, helping us see through walls or to the ocean’s depths? What allows humans to capture images of inside our bodies and black holes in outer space? What allows us to turn speech into text? What captures sound to recognize the music? What helps people with hearing loss hear better? Magic? No, Signal processing! It is the science that makes our senses digital—it lets us capture the information we hear and see (sounds, images, video) to be stored, sent and reproduced through our laptops, smartphones or tablets.
