15. Assume a three-bit message is to be transmitted. To clear the encoder two zero-bits are appended after message. Thus 5 bits are fed into the encoder to produce 10 coded bits (codeword). Assume that the channel error probability is p-0.1. If we observe 10,01,10,11,00 in the receiver what is the most likely transmitted sequence? (Hint: use Viterbi algorithms) Received sequence10 01 10 10

3. We want to transmit commands to a drone over a wireless channel. The commands and the probability of transmission are as follows: up (0.1), down (0.1), forward (0.4), left (0.15), right (0.15) and hover (0.1). (30) (a) What is a compact binary code to transmit these messages? (5) b) Suppose for hardware simplification reasons, a fixed 4-bit representation of each of the commands is used instead of the compact code. If a command is sent every second, how inefficient...

Say you have an n block of bits message. You split it to 8 bits each (assume that 8 divides n). For each of the 8 bit we choose a permutation of the bits. How many different codes could come out of this? Explain or prove the correctness of your analysis.

Consider a noisy communication channel, where each bit is flipped with probability p (the probability that a bit is sent in error is p). Assume that n−1 bits, b1,b2,⋯,b(n−1), are going to be sent on this channel. A parity check bit is added to these bits so that the sum b1+b2+⋯+bn is an even number. This way, the receiver can distinguish occurrence of odd number of errors, that is, if one, three, or any odd number of errors occur, the...

2. (20 points) Let's assume that we have to multiply two 3-bit positive numbers or two 3-bit negative numbers. That is, the signs of the input numbers are guaranteed to be the same. Draw a logic diagram for the modified multiplier. You can use any kind of combinational blocks such as multiplexors, half-adders, etc. Try to minimize the number of gates/blocks. 3.115 points] Find the answer for the following calculations.

Let's assume that rather than having a single representative firm we have 2 refiners of gasoline who have different marginal costs of reductions: MCRz = 0+2*Q2 (Note that these two cost functions are not going to give the economy wide MCR above in part A, so don't worry if this gives different results than above.) Each firm normally emits 6 units of pollution, so there would be 12 units of pollution total.

1. Let's assume that we want to fabricate a device with 3 lithography steps. During designing of a photomasks, what should we add in the photomask? (a) Negative lithography mask with alignment patterns in the first two masks. (b) Positive mask lithography mask with alignment patterns in the first two masks. (c) Alignment patterns in all masks without depending on the PR type. (d) Alignment patterns in the first two masks without depending on the PR type. 2. If a...
