In analog computing technology as well as in the laboratory study of control instrumentation or simulation systems, it is frequently desirable to be able to provide a given arbitrary periodic function as a forcing function. However, no device will reproduce exactly every arbitrary function which might be required. For this reason, considerable effort has been applied toward the development of devices which will reproduce an approximation to a wide variety of functions. The term, Â¿function generatorÂ¿ has been given to devices of this type.
