ROKI Interview Questions and Answers

Write a code to fill the water tank

Q1. How to measure slope of random voltage waveform?
Ans. 
The slope of a random voltage waveform can be measured by calculating the rate of change of voltage over time.
• Calculate the difference in voltage between two points on the waveform

• Divide the voltage difference by the time interval between the two points to get the slope

• Repeat this process for multiple points on the waveform to get an average slope
