9.5.C. Circuit Design Techniques

Try these first

1. 1.

   What is differential signaling?

   Hint

   Think about how noise can be minimized using two signals.

2. 2.

   What does a low-pass filter do?

   Hint

   Consider its effect on signal clarity.

3. 3.

   What is the primary advantage of differential signaling?

   • A) It increases the speed of the signal
   • B) It cancels out common-mode noise
   • C) It requires more circuit components

   Hint

   Think about how two opposite situations can balance each other.

4. 4.

   True or False: Low-Pass Filters are only used in audio applications.

   • True
   • False

   Hint

   Consider other types of signals that might need filtering.

5. 5.

   Design a mixed signal circuit including differential signaling and a low-pass filter. Explain the expected performance.

   Hint

   Consider the layout and component choices for effectiveness.

6. 6.

   Evaluate a system's performance before and after applying spread spectrum clocking. What parameters would you analyze?

   Hint

   Think about how each parameter relates to noise levels.
