This project report is based on the internal circuit of Function Generator. A number of instruments can be found in devices lab. Function generator is one of the most common ones. I have chosen this project to understand the function generator’s working and its internal structure. The designed circuit will give three waves (square, sine and triangle) of variable frequency at output. The detailed analysis of the circuit is done below. The circuit converts DC voltage into three different waveforms. The circuit is able to vary frequency by using rheostats.
