Abstract
Errors encountered in time differentiating a voltage signal with a simple high gain operational amplifier differentiator are studied. Numerical and electronic means of correcting these generally small errors are suggested. The circuit, including a linear sweep voltage source, used for photoemission studies in this laboratory is presented. The coefficient of the error terms for this particular circuit are calculated numerically. Presently achieved sensitivity and resolution are discussed.Keywords
