c) Tommie doesnt feel so good about the answer to part b) and wants to be 100% sure that there is no aliasing in the digital output of the A-D converter. After analyzing the signal, Tommie concludes that all signal of interest is in the 0-12kHz range and decides to build an anti-aliasing filter with a cut-off frequency of 15kHz. [3pts] What is the filter gain (in dB) at the cutoff frequency of 15kHz? What should be the stopband attenuation (Astop) and stopband frequency (Fstop)? Show your calculation.

The rotation of the arm OA about hinge O is defined by the relation $\theta = 0.15t^2$, where $\theta$ is expressed in radians and $t$ in seconds. The block B slides along the arm in such a way that its distance from O is $r = 3 - 0.40t^2$, where $r$ is expressed in meters and $t$ in seconds. Determine the total velocity V and the total acceleration $a$ of the block after the arm has rotated through $\theta = 30^\circ$.
