Problem: Write a program in Java to record the status of a tuning Circuit for a frequency ranges from Fmin to Fmax. Create a random access file for the process. A Variable capacitor is used ( Cmin = 15 PF and Cmax =365 PF) with increment of 15 PF. A typical tuning frequency is 16.7 MHz.

1- Read all the variables

ctypical=Math.sqrt(cmin*cmax);

L=(((2*Math.PI)/ftypical)/ctypical);

fmin=((2*Math.PI)/Math.sqrt(L*cmin));

fmax=((2*Math.PI)/Math.sqrt(L*cmax));

Cmin=15

Cmax=365

newf when the frequency changes

2- Compute the value for L

3- Compute the value of new frequency for different capacitor.

4- Compute the value of L as frequency changes

5- What will be the value of L at tuning frequency

6- If Fmax is greater than 16.7 MHz , go to the random access file and change the typical frequency to a new one Algorithm: F = 2 pi / sqrt(LC) Frequency minimum formula: Fmin = 2pi / sqrt(LCmin) Frequency Maximum formula = Fmax = 2pi/ sqrt(LCmax) C, for capacitor: C = sqrt(Cmin * Cmax) L = (2pi / F)^2 / C

Output: Display the values of L as it changes
