3. Correlation and Signal Decoding (a) Review the use of functions, then answer this question. Define a function decode such that it takes as inputs: a signal x, the width d of signal x, the sampling rate fs, the low signal xo, and the high signal x1, and then outputs the decoded symbol to the variable s. (b) Write a Python decision statement (if/else) to meet the following conditions: Let s be 0, unless the variable ylcorr is greater than the variable yocorr - in that case, assign the value 1 to s. 3.
