I need help figuring out the DAC feedback for this problem using
Multisim, I need to add to this circuit to convert the analog input
from 0V to 9V.

In this project you'll design a 4 bits Analogto Digital Converter (ADC) to convert analog input from 0 to 9 V and use it in a fire alarm detection system The digital part for this circuit is already provided and you'll need to work only with analog feedback. We'll use Multisim for simulation, the digital portion will be provided for you to add the analog one. The digital part of ADC is shown in Fig. 1. You need to add the feed back to compare the digitals output with the analog input using the comparator. The feedback is a digital to analog converter (DAC). It is used to stop the counter when it reaches the same analog input value.
