A Low-Cost Programmable Arbitrary Function Generator for Educational EnvironmentAbstractThis paper presents the design, implementation, and operation of a low-cost programmablearbitrary function generator intended for use as a plug-in board in a personal computer. Since adigital computer is used, capabilities such as programmability and signal recording are availablewith this system. Therefore, this instrument can generate any function of time that can berepresented mathematically. The ability to generate arbitrary waveforms makes this instrumentmore versatile that an ordinary function generator that can produce only a few differentwaveforms. This design offers a significant advantage to educators in underdeveloped countrieswith limited resources to obtain a low-cost instrument that can be used in undergraduatelaboratories where more expensive commercially arbitrary function generators are not available.One interesting application of this instrument is the synthesis of sound. If the equation for aparticular sound is known, the sound can be produced when this function generator is connectedto an audio amplifier and a speaker.
