The amplitude of a random signal uniformly distributed between - 5 V and 5 V. If the positive values of the signal are uniformly quantized with a step size of 0.05 V, and the negative values are uniformly quantized with a step size of 0.10 V, the resulting signal to quantization noise is approximately
