Complex to Real Website


Charan Langton

This site is full of well-written tutorials on wireless communications and DSP topics.

Communications is not an easy science. The math is heavy, and intuition is slow to develop. To complicate things further, the field does not stay put. New concepts are always coming to the fore. This website offers tutorials I have written on various topics in analog and digital communications that will help you cut through this complexity. I keep adding to this collection, albeit very slowly. Our field represents a pinnacle of human achievement in applied mathematics. During our engineering education, most of us don't develop the intuitive understanding of these beautiful ideas. I have tried to make these tutorials as simple as is possible given all the math required. I hope I have been successful in taking you closer to the "aha" moment.
