Summary:Methods, apparatus, systems and articles of manufacture are disclosed to measure a resonant sensor based on detection of group delay. An example apparatus includes a modulation manager configured to query the resonant sensor with a modulated signal including a frequency; and a resonance determiner configured to determine a resonance frequency of the resonant sensor based on a group delay associated with the resonant sensor and the frequency.
