Topic: Random Processes
The noise phenomena arranged in the order of their dominance when plotted as a function of increasing frequency are:
- A. Transit time noise, Flicker noise, White noise
- B. Flicker noise, White noise, Transit time noise
- C. White noise, Flicker noise, Transit time noise
- D. Transit time noise, White noise, Flicker noise
Answer: B. Flicker noise, White noise, Transit time noise
Explanation: Flicker noise (1/f noise) is dominant at low frequencies. White noise (thermal/shot noise) is flat and dominates the mid-frequency range. Transit time noise becomes dominant at very high frequencies.
