A 4-bit D/A converter is connected to a free-running 3-bit UP counter, as shown in the following figure. Which of the following waveforms will be observed at V_{0} ?
In the figure shown above, the ground has been shown by the symbol

\begin{array}{ccccccccc} AK& Counter && & DAC& & \\& \theta_{2} & \theta_{1} & \theta_{1} & D_{3} & D_{2} & D_{1} & D_{0} & \\1 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 \\2 & 0 & 0 & 1 & 0 & 0 & 0 & 1 & 1 \\3 & 0 & 1 & 0 & 0 & 0 & 1 & 0 & 2 \\4 & 0 & 1 & 1 & 0 & 0 & 1 & 1 & 3 \\5 & 1 & 0 & 0 & 1 & 0 & 0 & 0 & 8 \\6 & 1 & 0 & 1 & 1 & 0 & 0 & 1 & 9 \\7 & 1 & 1 & 0 & 1 & 0 & 1 & 0 & 10 \\8 & 1 & 1 & 1 & 1 & 0 & 1 & 1 & 11\end{array}
Now due to comparative: V_{0} will rise till 4th pulse, by on 5th pulse, V_{0} goes to 8 then again rises by 1 step.
