Interfacing a Transducer to an Analog-to-Digital Converter and Interfacing Digital-to-Analog Converters to Loads
The purpose of this lab is to allow students to gain experience constructing Digital to Analog Converters in Multisim. Students will extend the concepts learned in the module and homework to build an 8-Bit DAC. Several binary inputs and the associated analog output values measured with a virtual digital multimeter will be captured in screenshots.
