Does Cyton have guaranteed no missing codes?

  The Cyton is using the TI ADS1299 ADC chip. Full specs are on their website, See the 'data sheet' specs on that page,

  https://www.ti.com/product/ADS1299

  At the default gain, the Cyton has a 24 bit resolution of .022 microvolts per count.

  EEG signals below 1 microvolt are generally considered too noisy to have any validity. But the resolution is there. And the default x24 gain can be adjusted to other values if increased upper range is needed.

  ADS1299 uses a delta-sigma ADC amplifier. 'Missing codes' may be a misfeature of older technologies.
