Extracted text: b) The analogue signal is defined as: v (t ) = 5sin(2x 5001) + 5sin(2x 7501) is sampled as shown in Figure 2 to be converted to digital data. 10 8 6 4 2 -2 4 -6 -8 -10 Time (s) x 10 Figure 2 i. Determine the Nyquist rate. ii. Is this signal sampled optimally? State your reason. iii. Given the upper and lower bounds depicted on this graph, and it requires I volt of resolution or better, what is the minimum number of bits you need for each sample in your A/D converter? iv. Determine the exact resolution based on the answer in question iii. Volts
