What is the most simplest way to solve these following problems in C? Thanks
The purpose of this assignment is to simulate the transmission and reception of a text message (ie., character string) over a noisy communications channel. Suppose we wish to transmit the string "Hello." We can translate this string into a bit stream as shown below: String: He l I o. 10 (note: the last character 10 is the null terminator character) ASCII: 72 101 108 108 111 46 0 Binary: 01001000 01 100 101 01 101 100 0110 1100 01101111 00101110 00000000 Notice how this string can be expressed as 8 x 56 bits. Suppose we transmit each of these bits as voltages on an electrical signal (for simplicity, +1.0 V for binary 1 and 0.0 V for binary 0) We can simulate noise by encoding these bits in a double array of length 56 and then adding noise samples to the 1.0 and 0.0 values that will initially be loaded into the array. With a small amount of noise (low SNR), the values in this array for the first character "H" may be: 0.0143, 0.9985, -0.00124, 0.1076, 1.00325, 0.00173, 0.0563, 0.00474 With low noise, it is clear that the voltages "near" 0 represent binary 0 and the voltages "near" 1 represent binary 1. As a general rule, a receiver will take any voltages less than 0.5 and treat them as binary 0 and any voltages greater than or equal to 0.5 and treat them as binary 1 Problem 1: Write a function double message to signal (char message) that accepts a message as a string (appropriately terminated) and returns a dynamically allocated double array that contains the bit stream for this messages (as the values 1.0 for binary 1 and 0.0 for binary 0)
