2. In the real-world, humans hear sound as an analog signal. This means When sound is recorded or transmitted electronically, the continuous (analog) waveform is sampled to convert it to a discrete (digital) sequence. Sampling is the process of reducing a continuous-time signal to a discrete-time signal. As the sampling rate increases, the sound quality of the recording or transmission will improve. The graphs below represent two different samples of a pure tone. Sample 1 is taken 8 times per unit of time. Sample 2 is taken 16 times per unit of time. Sample 1: the signal is a continuous differently, as they process sound digitally, which is a discrete waveform. Student Guide (continued) a) Why would sample 2 reproduce a better replication of the pure signal? (2 points) b) Write a sinusoid model for Sample 2. (5 points)
