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

Questions & Step-by-Step Solutions

What is the Nyquist rate in the context of signal sampling?
  • Step 1: Understand that signals can have different frequencies, which are how fast the signal changes.
  • Step 2: Identify the maximum frequency of the signal you are working with.
  • Step 3: Calculate the Nyquist rate by multiplying the maximum frequency by 2.
  • Step 4: Recognize that the Nyquist rate is the minimum sampling rate needed to accurately capture the signal without losing information.
  • Step 5: Remember that if you sample below the Nyquist rate, you may experience aliasing, which distorts the signal.
