The Nyquist rate is defined as:
💡 Hint: Consider the implications of sampling at or below this rate.
True or False: Aliasing occurs when the sampling rate is greater than twice the highest frequency.
💡 Hint: Think about the conditions under which aliasing becomes an issue.

A music producer notices that higher notes are sounding distorted in their recordings. If the highest note played is 7 kHz, what minimum sampling rate should they be using, and why?
💡 Hint: Use the formula: Sampling Rate ≥ 2 × Highest Frequency.
During the analysis of a signal with frequency components up to 6 kHz, the sampled signal appears garbled. If the sampling rate was set at 10 kHz, analyze and discuss potential issues that might have arisen.
💡 Hint: Refer back to what aliasing means in practical applications.
