Chapter 5: Range and Resolution Flashcards
1
Q
How is the range shown for a converter?
A
The range of a converter will be quoted in bits for the digital side, e.g. a 10-bit ADC.
2
Q
How is the range measured?
A
The range on the analogue side will either be Volts or Amps.
A voltage measurement is often a differential value between two inputs.
3
Q
What is the resolution?
A
The resolution of a converter is the size of the smallest change that can be converted.
4
Q
What is the resolution in the digital domain?
A
In the digital domain this is the Least Significant Bit (LSB)
5
Q
What is the resolution in the analogue domain?
A
in the analogue domain, the theoretical resolution is the range / 2N , where N is the number of bits in the digital domain. Because the conversion process is imperfect the actual resolution may be worse.
