Adjust/fix the peak amplitude value

HI everyone,

Hope you are doing week and in good health. I need some help in modifying the code.In the following or attached Matlab file, I ma trying to generate the signal and then FFT. Then, inserting the awgn noise the certain frequencies points to show the peaks. But I am unable to fix the amplitude value whenever I run the file again and again. Every-time amplitude value is fixed. But my requirement to control the peak amplitude at fix value whatever I run 10 times but amplitude value should be fix at each peak. Just wondering if someone can help me and modify the code, it will really appreciable. Thanks for in advanced. If you need further clarification please don't hesitate tu contact with me on email [e-mail]

THnaks.

Regards, Aqib
