Signal Basics
Sampling & resolution: Prioritize ADC/DAC rate (Hz) and bit depth; higher ENOB improves faint-signal fidelity.
Bandwidth: Verify analog/RF and baseband bandwidth against your target signals; watch front-end roll-off.
Latency & jitter: Measure end-to-end latency and clock stability; low jitter preserves phase accuracy.
SNR & dynamic range: Compare effective SNR across gain stages; check noise floors under load.
I/O & buses: USB 3.x, PCIe, M.2, 10GbE—bus choice caps sustained throughput and capture burst depth.
Drivers & SDKs: Look for mature APIs (C/C++/Python), bindings, sample projects, and responsive updates.
File formats: WAV, HDF5, Parquet, Zarr—choose containers that preserve metadata and stream efficiently.
Calibration: Factory vs. field calibration, temperature drift specs, and linearity over frequency.
Compute targets: CPU/GPU/NPU/FPGA support, mixed-precision ops, and on-device accelerators.
Compliance & safety: FCC/CE/RED, emissions/EMC, isolation, and shielding for lab and field use.
Data Pulses
1. Pipeline readiness: ingestion, preprocessing (filters, resampling), and lossless metadata tracking.
2. Reproducibility: seed control, determinism flags, and environment lockfiles/containers.
3. Metrics that matter: F1/AUROC/PR-AUC for classifiers; SDR/STOI/PESQ for audio; MAE/RMSE for regression.
4. Benchmarks: publish dataset splits, baselines, and hardware details for apples-to-apples results.
5. Versioning: DVC/MLflow/Hugging Face for datasets, models, and experiments with lineage.
6. Throughput vs. latency: measure streaming fps, tail latencies (p95/p99), and warm-start costs.
7. Cost per inference: TCO models that include energy, egress, accelerators, and licensing.
8. Privacy & governance: PII handling, retention windows, and redaction/anonymization support.
9. Interop: ONNX/XLA/TensorRT export, runtime compatibility, and ops coverage.
10. Monitoring: drift, SNR degradation, and alerting on QoS/SLAs in production streams.
Hidden Frequencies
1. Perf-per-watt: NPU/FPGA can beat GPUs at fixed latency envelopes for streaming inference.
2. Memory ceilings: VRAM and memory bandwidth bottleneck FFTs and large-kernel convolutions.
3. Kernel fusion: Fused ops reduce cache misses and bus chatter—huge for spectrogram stacks.
4. Quantization gotchas: Post-training int8 may crush weak signals; consider per-channel scales.
5. Thermal throttling: Edge boxes can silently downclock under sustained DSP workloads.
6. Driver variance: Minor CUDA/ROCm/firmware revs shift determinism and timing jitter.
7. Hidden defaults: Auto-gain, denoise, AGC, or windowing can mask true device behavior.
8. Licensing traps: Node-locked toolchains vs. floating seats can stall CI/CD pipelines.
9. Air-gap modes: Offline activations and local model registries matter for secure labs.
10. Vendor vs. reality: Validate spec-sheet SNR and bandwidth with independent sweeps.
Waveform Wonders
1. SDR magic: a laptop + SDR can scan aircraft beacons, satellites, and local RF noise floors.
2. Real-time FFTs: Modern scopes compute tens of thousands of FFTs per second for live spectra.
3. Beamforming: Microphone arrays steer “hearing” to isolate voices in chaotic scenes.
4. Denoise AI: Diffusion and transformer denoisers recover speech from –5 dB SNR chaos.
5. Synthetic data: Procedural noise + simulators pretrain robust detectors before field runs.
6. Visualization bias: Colormaps alter perception—perceptually uniform palettes reduce errors.
7. Aliasing illusions: Under-sampling creates phantom tones; anti-alias filters are heroes.
8. Clock discipline: GPSDO/OCXO references lock multi-device labs to microsecond sync.
9. Ultra-low latency: FPGA inline DSP can cut path delays to microseconds for control loops.
10. Waveform generators: Arbitrary sources recreate entire environments for repeatable tests.
