Question: What is the Nyquist rate in the context of signal sampling?

Options:

1. The minimum sampling rate to avoid aliasing
2. The maximum frequency of the signal
3. The bandwidth of the signal
4. The average power of the signal

Correct Answer: The minimum sampling rate to avoid aliasing

Solution:

The Nyquist rate is defined as twice the maximum frequency of the signal, which is the minimum sampling rate required to avoid aliasing.
