What causes signal reflections in high-speed PCB traces?
Correct!
Wrong!
Signal reflections occur due to impedance mismatches along the transmission line.
Which parameter affects the speed of signal propagation in a PCB trace?
Correct!
Wrong!
The dielectric constant of the substrate affects signal speed.
What is crosstalk in high-speed design?
Correct!
Wrong!
Crosstalk is undesired coupling of signals between adjacent traces.
Why is controlled impedance important in high-speed PCB design?
Correct!
Wrong!
Controlled impedance ensures signal integrity and reduces reflections.
Which component is used to terminate a transmission line to prevent reflections?
Correct!
Wrong!
A resistor matching the characteristic impedance is used for termination.
What does rise time of a signal affect in high-speed PCB design?
Correct!
Wrong!
Faster rise time increases high-frequency content, impacting signal integrity.

How can designers reduce crosstalk in PCB layouts?
Correct!
Wrong!
Increasing spacing between traces and adding ground planes reduces crosstalk.
What is the effect of via stubs on high-speed signals?
Correct!
Wrong!
Via stubs cause signal reflections and degrade signal quality.
Why is differential signaling used in high-speed PCBs?
Correct!
Wrong!
Differential signaling reduces noise and improves signal integrity.
