Problem statement: design a small-signal voltage amplifier using bjt's that meets the following specifications: 1) voltage gain of 50 or more 2) minimum input resistance of 15 kω 3) output resistance less than 100 ω 4) maximum unclipped output of 2v peak-to-peak 5) power supply voltage of 9 v 6) lower current drain from supply voltage

hint: you may use a multi-stage small-signal amplifier to achieve desirable input resistance, voltage gain, output resisntace, etc. a common-emitter amplifier with an emitter resistance re, but without an emitter by-pass capacitor ce is good for high input resistance, common-emitter amplifier using an emitter bypass capacitor is good for high voltage gain, and the use of an emitter follower results in a low output resistance.

answer: hi

explanation:

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
