Q1. What is cross talk
Ans. 
Cross talk is the unwanted transfer of signals between different components or traces on a circuit board.
• Occurs when signals from one trace interfere with signals on another trace

• Can lead to signal distortion or errors in data transmission

• Prevented by proper spacing and shielding between traces

• Example: Cross talk between data lines on a PCB causing errors in communication

Q1. Thermal throttling explanation
Ans. 
Thermal throttling is a mechanism used to prevent a device from overheating by reducing its performance.
• Thermal throttling is a technique used in electronic devices to prevent overheating.

• When a device reaches a certain temperature threshold, it will reduce its performance to lower the heat generation.

• This can result in slower processing speeds or decreased battery life, but it protects the device from damage.
