adcquantization noise

ADC quantization noise is about:

a.0.1 lsb
b.0.3 lsb
c.0.5 lsb
d.1 lsb
 

adc quantization noise

the power of noise is 1/12 of LSB.
so the answer is 1/3 or 1/4 appro.
 

quantization noise power is LSB^2/12
so quantization error voltage is sqrt(LSB^2/12)=LSB/2sqrt(3)=LSB/(2*1.7)=0.3LSB
