2) Construct a block diagram for finding the result of the following addition labeling each input and output stage A=101010 B=110011

The data-input and data-select waveforms in Figure 7 are applied to the multiplexer. Determine the output waveform F in relation to the inputs.

Q 1. Determine the output voltage of the Digital-to-Analog Converter (DAC) in Figure 1(a) and plot it in Figure 1(c). The sequence of the four digit binary codes represented by the waveforms in Figure 1(b) are applied to the inputs. A high level is a binary 1and a low level is a binary 0. The least significant binary digit is Do.
