The amplitude of a random signal is uniformly distributed between $-5 \mathrm{~V}$ and $5 \mathrm{~V}$.
If the signal to quantization noise ratio required in uniformly quantizing the signal is $43.5 \mathrm{~dB}$, the step size of the quantization is approximately
- $0.0333 \mathrm{~V}$
- $0.05 \mathrm{~V}$
- $0.0667 \mathrm{~V}$
- $0.10 \mathrm{~V}$
