The Century-Long Evolution of Radio Receivers: From Hardware to Software
2025-05-30
In 1862, James Clerk Maxwell laid the theoretical groundwork for electromagnetic energy. Thirty years later, Heinrich Hertz demonstrated radio transmission and reception, ushering in the era of Hardware-Defined Receivers (HDRs). Over 150 years, receiver design shifted from a hardware-centric approach to a software-centric one, with Software-Defined Receivers (SDRs) dominating the landscape for the past two decades. This evolution highlights the dynamic interplay between hardware and software in technological advancement.
