What is the difference between low pass and high pass filter?
What is the difference between low pass and high pass filter? The key difference between high pass and low pass filter is that the high pass filter circuit passes signals of the frequency higher than the cut off frequency while the low pass filter passes signals of the frequency lower than the cut off frequency.

What is the difference between 2 stroke and 4 stroke?
What is the difference between 2 stroke and 4 stroke? Typically, a 2-stroke engine creates more torque at a higher RPM, while a 4-stroke engine creates a higher torque at a lower RPM. Four-stroke engines have more parts, therefore they are more expensive and repairs cost more. Two-stroke engines require pre-mixing of oil and fuel, […]
