Quantization-Noise Power Calculation
Given Parameters
- Peak-to-peak amplitude of sinusoidal signal = 1.536 V
- Number of quantization levels = 128
- Quantizer type = mid-rise uniform
Mid-rise Uniform Quantizer
- In a mid-rise uniform quantizer, the quantization levels are centered on the mid-point between two consecutive steps.
- The quantization step size (Δ) can be calculated as:
Δ = (Peak-to-peak amplitude) / (Number of levels - 1)
Δ = 1.536 / 127
Δ = 0.012096 V
Quantization-Noise Power Calculation
- The quantization error is the difference between the actual signal value and the quantized value.
- For a sinusoidal signal, the quantization error is uniformly distributed between -Δ/2 and Δ/2.
- The power of the quantization error can be calculated as the variance of the uniform distribution.
- The variance of a uniform distribution between -a and a is given by:
Var = (a^2) / 3
- In this case, a = Δ/2 = 0.006048 V
- Therefore, the quantization-noise power is given by:
Power = Var = (a^2) / 3
Power = (0.006048^2) / 3
Power = 12 x 10^-6 V^2
Therefore, the correct answer is option C, which is 12 x 10^-6 V^2.
Given Parameters
- Peak-to-peak amplitude of sinusoidal signal = 1.536 V
- Number of quantization levels = 128
- Quantizer type = mid-rise uniform
Mid-rise Uniform Quantizer
- In a mid-rise uniform quantizer, the quantization levels are centered on the mid-point between two consecutive steps.
- The quantization step size (Δ) can be calculated as:
Δ = (Peak-to-peak amplitude) / (Number of levels - 1)
Δ = 1.536 / 127
Δ = 0.012096 V
Quantization-Noise Power Calculation
- The quantization error is the difference between the actual signal value and the quantized value.
- For a sinusoidal signal, the quantization error is uniformly distributed between -Δ/2 and Δ/2.
- The power of the quantization error can be calculated as the variance of the uniform distribution.
- The variance of a uniform distribution between -a and a is given by:
Var = (a^2) / 3
- In this case, a = Δ/2 = 0.006048 V
- Therefore, the quantization-noise power is given by:
Power = Var = (a^2) / 3
Power = (0.006048^2) / 3
Power = 12 x 10^-6 V^2
Therefore, the correct answer is option C, which is 12 x 10^-6 V^2.
