NO C is the correct answer.
= 1.536/128,
= 0.012.
Now, squre of step size= 1.44 * 10^-4.
So, quantization noise power = 1.44^-4/12 and ans is= 12 * 10^-6.
= 1.536/128,
= 0.012.
Now, squre of step size= 1.44 * 10^-4.
So, quantization noise power = 1.44^-4/12 and ans is= 12 * 10^-6.

Here, Δ = mp/L (Because peak to peak say).
So Δ =1.536/128 = 0.012
So Now,
Quantization noise power = 0.012*0.012/12.
= 12*10 to the power -6.
So Δ =1.536/128 = 0.012
So Now,
Quantization noise power = 0.012*0.012/12.
= 12*10 to the power -6.
