What is the Nyquist rate?
Correct Answer: Nyquist rate is twice the maximum frequency of the signal.
- Step 1: Understand that signals can have different frequencies, which are how fast they change over time.
- Step 2: Know that when we want to record or process a signal, we need to take samples of it at certain intervals.
- Step 3: Realize that if we don't sample fast enough, we can lose important information about the signal. This is called aliasing.
- Step 4: Learn that the Nyquist rate is a rule that tells us how fast we need to sample a signal to avoid aliasing.
- Step 5: The Nyquist rate is equal to twice the highest frequency present in the signal.
