How an ADC turns a continuous waveform into numbers: sampling, aliases, quantization, ideal SNR, noise that folds, distortion, and DC errors. Same layout as Voltage Regulation and Impedance Matching — Key point, Along the way on the left, lab on the right.
Live
Continuous → discrete-time sequence \(x[n]\)
Nyquist fold — same samples, different truth
LSB, peak error, \(\sigma_e=\mathrm{LSB}/\sqrt{12}\)
6.02N + 1.76 walked through
Density, bandwidth, and fold
THD / SFDR vs ideal floor
Offset, gain, INL, DNL
Planned
Ref errors that eat ADC bits
Cutoff vs \(f_s/2\)
Skew, settle, channel phase
Sinc nulls; 50/60 Hz rejection
Architecture for DC precision
