Q1. ADC in embedded?
Ans. 
ADC stands for Analog-to-Digital Converter, used in embedded systems to convert analog signals to digital data for processing.
• ADC is essential in embedded systems for converting real-world signals (such as temperature, light, sound) into digital data that can be processed by the microcontroller.

• ADC resolution determines the number of bits used to represent the analog signal digitally. Higher resolution means more accur...read more

Q2. How d you calculate piston cylinder speed after power phase
Ans. 
The piston cylinder speed after the power phase can be calculated using the formula: speed = distance / time.
• Calculate the distance traveled by the piston during the power phase.

• Determine the time taken for the power phase.

• Divide the distance by the time to calculate the piston cylinder speed.
