# FFT resolution and record length
# Scope: Uniform sampled FFT frequency-bin spacing; no spectral interpolation.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

sampleRate = 1000 Hz
samples = 1024

binWidth := sampleRate/samples [Hz]
recordLength := samples/sampleRate [s]

check frequency resolution budget: binWidth <= 1 Hz

scenario alternative: sampleRate = 800 Hz
