B)Square
C)Bathtub
D)Uneven

Question

Quizplus · Accepted Answer

The overall noise-intensity versus frequency curves for semiconductor devices typically have a bathtub shape. This is due to the two main sources of noise in the devices: thermal noise and shot noise. At low frequencies, thermal noise dominates, contributing to a flat or slowly-rising noise-intensity curve. At high frequencies, shot noise dominates, contributing to a steeply-rising noise-intensity curve. The dip in between the two peaks creates the bathtub shape.
