4. If a 6-bit binary number is used to represent an analog value in the range from -63 to 126, 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?

Homework Answers

Answer #1

The range of the analog value is -63 to 123 i.e. total (123+63+1)= 190 analog value is to be represented.(1 is added for the 0). Now the binary number is 6. I.e. a 6 bit binary number can represent 26 values i.e. 64 numbers can be represented by a 6 bit binary number...

therefore the accuracy of this system is

(total value can be represented/ total value is to be represented)× 100

=>(64/190) ×100

=> 33.69%

in other words, if the binary number is incremented by 1,the corresponding change in analog number will be

190/64 = 2.968

so the accuracy is (change in binary/ change in analog)

=>(1/2.968) ×100= 33.69%

If you have any doubt,you can ask me in the comment box... Thank you...

Adder Start out by picking 2 positive six bit binary numbers that are less than 3210, written in 2's complement notation. The eventual goal is to add these two numbers. 1) Look at the LSB bit of the numbers, and using logic gates (NANDs, NORs, etc.) design a circuit that correctly gives the right output for any possible combination of bits in the LSB place. 2) Now look at the next column to the left (next to LSB). In this...

This assignment involves using a binary search tree (BST) to keep track of all words in a text document. It produces a cross-reference, or a concordance. This is very much like assignment 4, except that you must use a different data structure. You may use some of the code you wrote for that assignment, such as input parsing, for this one. Remember that in a binary search tree, the value to the left of the root is less than the...
