Sure thing, let’s turn that sketch into a working thing. I’d start with a low‑jitter, low‑phase‑noise oscillator and feed it into a phase‑locked loop that locks onto your rhythm. Then use a spread‑spectrum modulator to tuck the data into the quiet envelope. We’ll keep the duty cycle tight and add a little digital filtering to wipe out any side‑band bleed. Once we nail the timing, I can breadboard a prototype with an FPGA or a microcontroller and tweak the jitter in real time. How fast do you need the cycle, and what bandwidth are we targeting? That’ll shape the component choices.
