Q
Q: What is the Nyquist rate in communication systems?
Solution:
The Nyquist rate is the minimum sampling rate required to avoid aliasing, which is twice the maximum frequency of the signal.
Steps: 6
Show Steps
Step 1: Understand that signals can have different frequencies, which are how fast they change.
Step 2: Know that when we want to capture or record a signal, we need to take samples of it.
Step 3: Realize that if we don't take enough samples, we can get a distorted version of the signal, called aliasing.
Step 4: Learn that the Nyquist rate is a rule that helps us avoid aliasing.
Step 5: The Nyquist rate says we need to sample the signal at least twice as fast as the highest frequency in the signal.
Step 6: If the highest frequency of the signal is 'f', then the Nyquist rate is '2f'.
