1. Suppose that *n* = 128, , , and . Here, *n* is the total number of samples in a signal and *dt* is the sampling time interval in seconds. What is the sampling frequency ? [Answer: 250 Hz.] What is the Nyquist frequency ? [Answer: 125 Hz.] What is the sampling frequency interval *df*? [Answer: 1.95313 Hz.]

2. Discuss what you see on the sketches shown in Figure I-1.
