(Solved): Draw the circuit of a BCD adder for adding two single BCD digits A=a3 a2 a1a0 and B=b3b2b1b. ...

Draw the circuit of a $$\mathrm{BCD}$$ adder for adding two single $$\mathrm{BCD}$$ digits $$\mathrm{A}=\mathrm{a}3$$ a2 $$\mathrm{a}1\mathrm{a}0$$ and $$\mathrm{B}=\mathrm{b}3\mathrm{b}2\mathrm{b}1\mathrm{b}$$. Simulate the circuit in CEDAR logic or any other tool for the following cases (i) $$\mathrm{A}=4$$ and $$\mathrm{B}=3$$ (ii) $$\mathrm{A}=7$$ and $$\mathrm{B}=4$$ (iii) $$\mathrm{A}=9$$ and $$\mathrm{B}=8$$ Provide screenshots of the circuit schematics and the simulation waveforms Note: The 4-bit adder is available as a single block in the "Add and Compare" section of the components library in CEDAR logic
