Questions for you to try 1. Convert each of the following values to an 8-bit unsigned binary value. a) 3510 b) 10010 c) 22210 d) 145 10 2. If an 8-bit binary number is used to represent an analog value in the range from 0,, to 100,0, What does the binary value 01100100, represent? 3. If an 8-bit binary number is used to represent an analog value in the range from 32 to 212, what is the accuracy of the system? In other words, if the binary number is incremented by one, how much change does it represent in the analog value? 4. Assume a digital to analog conversion system uses a 10-bit integer to represent an analog temperature over a range of -25°F to 125°F. If the actual temperature being read was 65.325°F, what would be the closest possible value that the system could represent?

1. This question is about Binary Arithmetica. Calculate, showing all stages of your working, the representations of the following decimal numbers in 8-bit two’s complement:m = -61 p = -6n = -3 q = 43o = 15 r = -86b. Calculate, showing all stages of your working, using 8-bit two’s complement, the sums: m + n, n + o, m - o, p - q, r + q and q + (p - m).
(a) For the following two cases, please determine the radix r:(BEE)r = (2699)10(365)r = (194)10(b) Please add, subtract, and multiply in binary:100100 and 10110(c) Please add the following numbers in binary using 2’s complement to represent negative numbers.Use a word length of 6 bits (including sign) and indicate if an overflow occurs:(-11) + (-4) = ?11 + 9 = ?(-10) + (-6) = ?(d) Assume the following three cases are correct and assume three digits are used to represent positiveintegers. Determine the base of the numbers. Did any of the additions overflow?654 + 013 = 000024 + 043 + 013 + 033 = 223024 + 043 + 013 + 033 = 201
Dont use others answers please!! will leave you feedback!! Thank you! 5. b. Suppose we wanted to test or check Bit 2, in the byte 01101100, to see if it was a 0 or 1. Show the value, mask and the result of the bitwise logical operation.
