Signals are an inherent part of our daily lives, often existing unnoticed in the background. These powerful tools enable efficient communication between individuals, devices, and even celestial bodies. Signals are transmitted through various mediums such as sound waves, light, or electrical impulses. They carry valuable information that is decoded by receivers, allowing messages to be understood and actions to be undertaken. From the traffic signals directing us on the roads to the signals bouncing off satellites for global communication, their impact cannot be overstated. Understanding the significance of signals opens doors to improved communication, fostering better interactions in our increasingly connected world.
