What is the primary reason for using DSP in modern Mixed-Signal Designs?
a) To eliminate the need for any analog components.
b) To mathematically correct analog shortcomings like mismatch and non-linearity.
c) To make the chip run at lower clock speeds.
d) To replace the Power Amplifier.
What does "ENOB" stand for in ADC testing?
a) Every Node On Board
b) Effective Number of Bits
c) Electronic Noise Over Bandwidth
d) Electronic Noise Over Bandwidth
Where should an ADC be placed relative to a CPU?
a) Directly adjacent to the CPU to minimize digital interface delay
b) Near the center of the chip to balance routing lengths
c) Close to the analog input and far from the CPU to minimize digital noise coupling
d) Inside the CPU block to simplify clock distribution
