Abstract
A novel “ramp-waveform sampling technique” for accurate and fast speed measurement is presented. Square pulses from an encoder are turned into ramps using analog electronics. They are then sampled, and linear regression is used on ramp-waveform sample points to extrapolate backward and determine the starting point of each pulse very accurately
