:in a crc error-detection scheme, choose p(x) = χ4 + χ2 + 1 + 1 a. encode the bits 10010011011 b. introduce an error pattern 10001 (i. e invert the digit in the code word where "i" appears in the error pattern sequence.) and see if the error can be detected c. introduce an error pattern 10111 and see if the error can be detected

*write a program that defines symbolic names for several string literals (chars between quotes). * use each symbolic name in a variable definition. * use of symbolic to compose the assembly code instruction set can perform vara = (vara - varb) + (varc - vard); ensure that variable is in unsigned integer data type. * you should also further enhance your symbolic logic block to to perform expression by introducing addition substitution rule. vara = (vara+varb) - (varc+vard).
