Stimulation and pulse generators
Electrical electrodes and magnetic coils return different kinds of input. Cerebro coordinates their session context while each output system owns its waveform, monitoring and controls.
The recovered waveform-generator work
The notes develop a programmable waveform instrument: combine characterized physical signal bases under a shared clock, measure the actual result, and account for the load. This is the link between the pulse-generator ideas and Cerebro's session architecture.
Calibration and output monitoring close the instrument loop.
Low-level waveform generation and transducer characterization.
Defined bench outputCarrier, pulse and transport experiments with a calibrated receiver.
Separate RF pathPhysical pulse bases evaluated at an instrumented electrical or coil load.
Bench characterizationPulse-forming lines and networks, resonant bursts and delayed signal bases provide a library of shapes to characterize.
The earlier thyratron and triggered-gap sketches sit alongside semiconductor-cell concepts. Timing jitter, recovery and the load constrain what a source can reproduce.
The controller works from measured transfer functions and independent output monitors. A target waveform and the waveform delivered at a load are separate records.
These are shared-instrument research families, not a selected human-use TMS circuit or a complete-system component budget.
What integration means
Record the device, coil or electrode arrangement, geometry and allowed operating mode. Keep body-contact equipment distinct from bench-load instruments.
Keep intended events, device status and independently measured output separate. The external system retains its own enable chain, stop controls and qualified operator interface.
After output stops, test acquisition recovery, field conditions and sensor status. A clean-looking trace alone is insufficient to establish a usable neural measurement.
The chair supplies support, a qualified mounting interface and isolated pose/fault status. Its status contacts do not generate pulses. Movement and massage are excluded during TMS; the external system owns coil cooling and positioning requirements.
