The two variables loaded into the workspace are muxsignal and fs. the raw data stream of the music signals is stored in muxsignal while fs contains the sampling frequency. determine the sampling period, store it inside the variable ts and then use this to construct a time domain vector, t, that corresponds to muxsignal. plot muxsignal against this time vector.

Convert and simplify the following sentences to conjunctive normal form (cnf): (a) (p → (q → r)) → (p → (r → q)) (b) (p ∧ q) → (¬p ↔ q) (c) ((p → q) ∧ ¬q) → ¬p

Read the code below. what will the computer print if the input for year_variable is 1700? if year_variable == 1776: print("your answer is correct. the declaration of independence was signed in “year_variable”.") elif year_variable < 1776: compute_variable = 1776 - year_variable. print("add “compute_variable“ years to your answer for the correct answer.") elif year_variable > 1776: compute_variable = year_variable - 1776 print("subtract “compute_variable” years from your answer for the correct answer.")

Consider the following function main: int main() { int alpha[20]; int beta[20]; int matrix[10][4]; . . } a. write the definition of the function inputarray that prompts the user to input 20 numbers and stores the numbers into alpha. b. write the definition of the function doublearray that initializes the elements of beta to two times the corresponding elements in alpha. make sure that you prevent the function from modifying the elements of alpha. c. write the definition of the function copyalphabeta that stores alpha into the first five rows of matrix and beta into the last five rows of matrix. make sure that you prevent the function from modifying the elements of alpha and beta. d. write the definition of the function printarray that prints any onedimensional array of type int. print 15 elements per line. e. write a c11 program that tests the function main and the functions discussed in parts a through d. (add additional functions, such as printing a two-dimensional array, as needed.)
