Signals, an essential component of our day, often go unnoticed. From regulating traffic to transmitting information across vast distances, signals play a pivotal role in maintaining order and ensuring smooth communication. Signal processing is a crucial field in technology, advancing our capabilities in telecom, computing, and healthcare. Simultaneously, signals relayed by our bodies, like a frown or smile, convey emotions and create social harmony. Celebrating the unnoticed, yet profound influence of signals underscores humanity’s reliance on sound, light, and touch for communicating seamlessly in our intertwined global community.
