Ques.3: Consider the addition of n-bit numbers on a machine of width n-bits. Specifically, the two n-bit 2’s complement numbers A=an-1,an-2,…a1,a0 and B=bn-1,bn-2,…b-1,b0 are added to get the n-bit sum C=cn-1,cn-2,…c1,c0. Provide a Boolean function F (defined in terms of the input variables ai and bi and output variables ci, where 0 <= i < n ) that determines if an overflow has occurred in this addition – the function should be expressed in terms of input variables. F should...

(1) Consider a noisy wireless channel which flips each bit ( 0 becomes 1 or 1 becomes 0 ) with probability p. To guarantee the information is received reliably, each bit is transmitted m times (called repetition coding). For example, if m = 3 and “0” needs to be sent, you transmit “000” instead of “0”.

1. A transmitted message bit B is either 1 or 0, each with equal likelihood. The bit is captured by N independent receivers; each receiver has a probability p of receiving the wrong bit value (e.g. receiving a 1 when a 0 was sent). Write the conditional probability that the message bit is 1, if all N receivers receive a 1. Write your answer as a function of p.
