My task only to design the DAC circuit(Dgital-to analog converter).Meaning that, i only need to convert the signal in digital form into analog signal back.My previous question is more focus in design the DAC circuit(hardware).It seems likely,the voice recorder and feedback function, but implement with voice recognition system. In order to design the DAC circuit,I were advice do not use any of IC chip.Can anyone help me to solve this problem?..

Hi, Sorry to disturb u all.I'm a new member in this forum.Hopefully,anyone can help me by sharing info,any ideas,comment or suggestion due to help me finished my final year project.Here, i need to design DAC part of voice recognition system.I need to design DAC circuit and the same time doing matlab simulink to sample this voice. How do i can identify either my DAC circuit, function or not?What kind of source do i need to connect with my circuit, if i need the signal in digital form?Where and how do i handle it?
