1. Using the ASCII table of English alphanumeric characters, download the decimal codes of the two letters of your surname: the second letter and the third letter. Convert them to binary code. 2. Using the standard transformation algorithm, transform the decimal codes of letters obtained in point 1 into: a) octal code b) hexadecimal code c) minus binary code d) binary-coded decimal code (BCD). 3. Convert the bit codes of the letters received in point 1 to the modified U1 and U2 binary codes. Perform addition of numbers in these systems with different combinations of their characters: ++, 4. Take 6 bits from right side of binary code of the second letter your surname. Convert this code to the modified U1 system as a negative number. Then take 6 bits from right side of binary code of the third letter your surname. Convert this code to the modified U1 system as a negative number. Perform multiplication of these numbers. 5. Take 6 bits from right side of binary code of the second letter your surname. Convert this code to the modified U2 system as a negative number. Then take 6 bits from right side of binary code of the third letter your surname. Convert this code to the modified U2 system as a negative number. Perform multiplication of these numbers. 6. Design the digital combinational systems (truth table, Karnaugh map, logic gate system): a) full adder in one bit, b) parallel 8 bit adders in U1 and U2 systems
