Abstract

Lab 6 instructed us to design a digital to analog converter in order to generate a square wave which would drive a speaker connected to the supplied FPGA. We also needed to be able to set the amplitude of the generated signal using the DIP switches present. This lab was very useful to show the basic theory behind digital to analog converters which need to turn digital values into actual signals. Also, this square wave generator is very useful in creating complicated audio signals which are composed of square waves of varying frequency.
