Goal is to design a 4th - order iir butterworth bpf with center frequency 100 hz and bandwidth 40 hz. 1.choose an appropriate sampling rate (e. g., 300 hz) and determine the sample period.2.pre-warp the center, lower, and upper cutoff frequencies using, 휔휔푝푝=2푇푇tan(푇푇2휔휔)3.create a normalized analog 4th-order butterworth lpf (normalized filter will have cutoff of 1 rad/sec), and apply lp to bp transform, using the prewrapped frequencies in step 3. 4.apply bilinear transform to create a digital filter, 퐻퐻(푧푧). 5.plot frequency response of both bpfs,퐻퐻(푠푠) and 퐻퐻(푧푧).

answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

//main function

int main()

{

  // variable

 int n;

 cout<<"enter a number:";

 // read the input

 cin>>n;

 // find the square root of the absolute value

 float square_root=sqrt(abs(n));

 // print the square_root

 cout<<"square root of "<<n<<" is: "<<square_root<<endl;

  return 0;

}

Explanation:

Read a number from user and assign it to "n".Then find its absolute value with abs() function.Then calculate the square root of the absolute value with sqrt() function.Print the square root of the number.

Output:

enter a number:-17

square root of -17 is: 4.12311
