2. (50 points) We will be analyzing the signal to quantization noise ratio of the additive quantization noise model shown below with noise shaping filter $G(z)$ and downsampling factor $M$. The discrete-time quantization noise sequence $e[n]$ is a zero mean white random sequence satisfying all of the properties on page 214 of your textbook (also covered in Screencast 5.2) with autocorrelation $\phi_{ee}[m] = 0.01 \cdot \delta[m]$, i.e., $\sigma_e^2 = 0.01$. The power spectrum $\Phi_{xx}(\omega)$ of the input signal $x[n]$ is given as $$ \Phi_{xx}(\omega) = \begin{cases} 1 & |\omega + 2r\pi| \leq \frac{\pi}{4} \\ 0 & \text{otherwise} \end{cases} $$ with $r \in Z$ such that $\Phi_{xx}(\omega)$ is periodic with period $2\pi$. The LPF prior to downsampling in the system below is assumed to be ideal with a passband gain of one. Figure 2: Oversampled ADC with two-stage noise shaping (a) (10 points) Suppose $G(z) = 1$ and $M = 1$. Compute the signal to quantization noise ratio in dB at the output of the downsampler. (b) (20 points) Suppose $G(z) = 1$ and $M = 2$. Compute the signal to quantization noise ratio in dB at the output of the downsampler. For what positive integer value of $M$ is the signal to quantization noise ratio maximized subject to the requirement that the LPF prior to downsampling does not remove any of the desired signal $x[n]$? (c) (20 points) Suppose $G(z) = 1 - z^{-1}$ and $M = 2$. Compute the signal to quantization noise ratio in dB at the output of the downsampler.
