Objectives * Use a programmable IIR filter to generate a single frequency sine wave. * Use PWM to generate an audible output tone over the Basys MX3 speaker. * Display the frequency of the synthesized sine wave on the $$H(z) = \frac{Y(z)}{X(z)} = \frac{\sum_{i=0}^{M-1} b_i \cdot z^{-i}}{\sum_{k=0}^{N-1} a_k \cdot z^{-k}} = \frac{b_0 + b_1 \cdot z^{-1} b_2 \cdot z^{-2} + \cdots b_{M-…
