Abstract
This paper aims to generate the various waveforms commonly used in a laboratory. A computer is used to synthesize the waveforms. It makes use of software to synthesize the waveforms digitally and a Universal Serial Bus (USB) to parallel converter to transmit the digital version of the waveform to a digital to analog converter where it is converted to produce an analog waveform. A buffer is used to display the analog signal on an oscilloscope. Direct Digital Synthesis (DDS) is used to generate these waveforms. MATLAB simulation software is used to perform the DDS, and PROTEUS software is used for circuit design of the digital to analog converter.
