Communication has come a long way, from basic signals like smoke to complex systems we use today. Historically, communication began with basic sound and visual signals, evolving into electrical telegraphy in the 19th century and eventually paving the way for wireless communication after the introduction of different signals now there was a need for modulation so that these signals travel far and work well

Amplitude Modulation (AM) feels like stepping into the historical roots of broadcasting, where the strength of the signal itself carries our message. By altering the amplitude of the carrier wave according to the information we send, AM offers simplicity but at the cost of efficiency.

Double Sideband Suppressed Carrier (DSBSC) takes us a step forward by transmitting both sidebands without the carrier, which is like sending a message with less overhead. It's a clever way to save energy, though it demands a bit more from our tech.

Single Sideband (SSB) is where efficiency peaks, transmitting only one sideband to communicate across vast distances with minimal power, akin to sending a whisper that can travel the globe.

In MATLAB, I explored the essentials: sine and cosine waves. Playing with amplitude, frequency, phase, and time, I learned how these factors dance together to shape the waves that power our digital world

Each technique I've learned opens up new dimensions in how we can communicate, ensuring that signals are not just sent but sent right, with clarity, efficiency, and innovation at the core. This exploration has not only broadened my technical skills but also my appreciation for the art and science of signal transmission.
