請問用10’s complement 7523-4.567如何計算🙏

1.21謝謝！

-801. complement form and perform the following operations (note that the sum is +10,627 and requires five digits and a sign). (a) (+9,286) + (+801) (c) (-9,286) + (+801) (b) (+9,286) + (-801) (d) (-9,286) + (-801) signed-2's-complement Termissh. Di sdi 101 1.20 Convert decimal +49 and +29 to binary, using the representation and enough digits to accommodate the numbers. Then perform the binary equivalent of (+29) + (−49), (−29) + (+49), and (−29) + (−49). Convert the answers back to deci- mal and verify that they are correct. 1.21) If the numbers (+9,742)10 and (+641)10 are in signed-magnitude format, their sum is (+10,383)10 and requires five digits and a sign. Convert the numbers to signed-10's- complement form and find the following sums: (a) (+9,742) + (+641) (c) (−9,742) + (+641) (b) (+9,742) + (-641) (d) (−9,742) + (−641) 1.22 Convert decimal 9,045 and 337 to both BCD and ASCII codes. For ASCII, an even parity bit is to be appended at the left. (1.23) Represent the unsigned decimal numbers 609 and 516 in BCD, and then show the steps necessary to form their sum.

請問b跟d 🙏

1.30 plz用中文講解謝謝！

The message "Pass 0.12" is to be sent via communication line. For this, each character of the message should be encoded into a seven-bit ASCII code including the period and the it. Write the expression for the message sent. space. Each ASCII encoded character should be then encrypted by adding binary 101 to 1.29* Decode the following ASCII code: 10000110101110 1000010 1000001 1000010 1000010 1000010 1000111 1000101. 1.30 The following is a string of ASCII characters whose bit patterns have been converted into hexadecimal for compactness: 47 2E 5C 42 CF CF CC C5. Of the eight bits in each pair of digits, the leftmost is a parity bit. The remaining bits are the ASCII code. (a) Convert the string to bit form and decode the ASCII. (b) Determine the parity used: odd or even?
