High speed integrated circuitry can be used to realize a tachometer with a high sampling rate at slow speeds. This device would, under certain conditions, be useful in damping transients of fairly fast velocity- and position control systems. After a treatment of the errors which are inherent in this device and other conventional tachometers, a comparative study is made of the effects of digital tachometer on relatively simple feedback control systems. Methods to improve the response are studied.
