Suppose a binary message is transmitted through a noisy channel. the transmitted signal s has uniform probability to be either 1 or -1, the noise n follows normal distribution n (0, 4) and the received signal is r s+ n. assume the receiver conclude the signal to be 1 when r 2 0 and-1 when r< 0. 1. what is error probability when one signal is transmitted? 2. what is error probability when one signal is transmitted if we triple the amplitude of the transmitted signal? it means s 3 or -3 with equal probability. 3. what is the error probability if we send the same signal three times (with amplitude 1), and take majority for conlusion? for example, if three received signal was concluded 1,-1,1 by receiver, we determine the transmitted signal to be 1

check the picture below.

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%
