Functional Electromagnetism
summary
Uses GNU Radio, a HackRF transmitter and an RTL‑SDR receiver to show functional patterns in DSP by actually building a Morse‑code flowgraph that transmits on 430 MHz and is received in real time. Demonstrates composition as hierarchical block wiring, treats amplification and domain conversions as functors, and models time↔frequency via natural transformations implemented with FFT/IFFT. Exports to Python with heavy kernels in C, the demo runs live and illustrates concrete mappings between type‑like categories and signal processing blocks.
