Calcolatore Bit Rate — Formula

ADC Resolution

Formulas

LSB = V_ref / 2^N

Levels = 2^N

Dynamic Range = 20 x log10(2^N) dB

N is the number of bits. Each additional bit doubles the resolution and adds 6 dB of dynamic range.

Esempio Risolto

12-bit ADC with 3.3 V reference.

  1. Levels = 2^12 = 4096
  2. LSB = 3.3 / 4096 = 0.000806 V = 0.806 mV
  3. Dynamic range = 20 x log10(4096) = 72.2 dB
