computor assignment

Part F:
Write, compile and execute a C program with appropriate comments included that
calculates parameters of a common-emitter audio amplifier

The specified parameters:
Vc= 6.5 (v)
Ve= 1.3 (v)
Ic = 3*10
-3
(A)
Hfe= 100
Parameter to be calculated:
R1, R2, R3, R4 and Vout
Explanation
To write this program you do not need to know all aspects of the audio amplifier design.
As a programmer, you just need to understand the application area, the application
constraints and the algorithm employed for producing results.
The first step is to identify:
  input data
  output data
  a sequence of operation to produce the output data
The program input dataare: Vcc, Vc, Ve, Vin, Ic and Hfe
The input parameter that the program prompts the user to enter are:
  Vin, which can be any value in the range 0.01 – 0.05 (v)
  Vcc, which can be 9.0, 10.0, or 12.0(v)
In this assignment it is assumed that Vin and Vcc are entered correctly by the user. Other
input parameters Ic, Vc, Ve, and Hfe must be defined as constants.
The output dataare values of: R1, R2, R3, R4 and Vout
The algorithm to calculate R1, R2, R3, R4 and Vout is a simple sequence of operations:
1. Calculate the base current: Ib= Ic/Hfe  ( A )
2. Calculate R1 = (Vcc–Vc)/ Ic  ( ohm )
3. Calculate R2 = Ve/ (Ic+ Ib)( ohm )
4. Calculate Vb= Ve+ 0.7( v )
5. Calculate R4 = Vb/ ( 5 * Ib)( ohm )
6. Calculate R3 = (Vcc– Vb)/( 6 * Ib)( ohm )
7. Calculate Signal Amplification
Ks= R1/R2
8. Calculate Output signal
Vout= Vin* Ks   ( v )
,which you need to implement in your C program.
The application constraints:
- All calculation must be carried out with floatprecision.
- The calculated values of R1, R2, R3 and R4 must be displayed as integer numbers.
- Vout must be displayed with one decimal points precision.
- Output must be properly aligned in columns (see the example below).
Regardless what the compiler you have used working on this assignment, make sure that
your program can be compiled by gccusing the following command:
gcc –o main.exe –Wall -ansi main.c
and produces main(executable file).
Having been run, your program should produce output formatted as shown below :
Enter Vin: 0.02
Enter Vcc: 10
====================
Resistors:
R1 = 1624 ohm
R2 = 272 ohm
R3 = 42500 ohm
R4 =  9000 ohm
Output voltage:
Vout =  0.5 v
