A continuous-time signal $x_c(t)$ is bandlimited to $\omega_M = 71\pi$ radians/second. The signal is sampled with sampling frequency $\omega_s = 307\pi$ radians/second and then reconstructed with a zero-order hold reconstructor with frequency response $H_0(j\omega)$. What is the value $|H_0(j\omega)|$ for $\omega = 71\pi$ radians/second? Specify your answer to four decimal places.

43 Let $ Z_{1}, \ldots, Z_{n} $ be a random sample from $ N\left(0, \theta^{2}\right), \theta>0 $. Define $ X_{t}=\left|Z_{i}\right| $, and consider estimation of $ \theta $ and $ \theta^{2} $ on the basis of the random sample $ X_{1}, \ldots, X_{n} $. (a) Find the UMVUE of $ \theta^{2} $ if such exists. (b) Find an estimator of $ \theta^{2} $ that has uniformly smaller mean-squared error than the estimator that you found in part (a). (c) Find the UMVUE of $ \theta $ if such exists. (d) Find the Pitman estimator for the scale parameter $ \theta $. (e) Does the estimator that you found in part (d) have uniformly smaller meansquared error than the estimator that you found in part (c)?
