Step $2.$ Turn on the power supply and apply a clock frequency of $10$ kHz to the cascaded counters. Apply $10$ V to the reference input $($VREF$)(+),$ pin $14.$ Observe the analog output with an oscilloscope as the digital input continuously increases, recycles to zero, and increases again. Draw the output signal in Figure $2$a$.$

Step $3.$ Reduce the reference voltage at pin $14$ to $5$ V and observe the analog output with the oscilloscope. Draw the output signal in Figure $2$b$.$

Step $4.$ Increase the reference voltage at pin $14$ to $10$ V and remove the lead at pin $5$ of DAC$0808,$ observe the analog output with the oscilloscope. Draw the output signal in Figure $2$c$.$

Step $5.$ Submit the simulation file for Task $2$ without errors along with the report for verification purposes.

Identify the output voltage if the reference Input voltage $($VREF$)(+)$ at pin $\backslash (14=10\backslash$mathrm$\{$~V$\}\backslash ).$ Record and show the voltage output signal on the oscilloscope in Figure $2$a$.$

Answer:

$1.$ Digital Input waveform:

$2.$ Output voltage:
