clear; clc; close;

// Given data
I_p = +25; //Third order intercept point in dBm
MDS = -85; //noise level in dBm

//Calculations

dynamic_range = 2/3*(I_p -MDS);
printf("The dynamic range of the spectrum analyser = %d dB",dynamic_range);

//Result
// The dynamic range of the spectrum analyser = 73 dB
