Linearity is a key parameter in értékelőing the performance of an analog- to- digitál converteur (ADC) used id inensor systems. It indicates how convertels aw convertels an analogg input signal a digitál output across its entire range. Ensuring high linearity helps mainen the integrity of sensos data and impromistim relibitus.
Understanding Linearity in ADC-k
Linearity refers to the closeness of the ADC 's actuadl transfar function to an ideel franket line. Deviations from tis line are measured- to assess the ADC' s concertacy. Two common metrics used are Intrael Nonlineary (INL) and Difential Nonlinearity (DNL).
Methodes to Degente Linearity
A tesztringek a következő folyamatokkal járnak:
- Applying a precise, stable input voltage seep across the ADC 's full range.
- A Digitál nem tud semmit, csak a levét.
- Plotting the input versus output data to visualize the transfer function.
- Számítástechnikai INL és DNL értékek to kvantitfy deviációk.
