void print_fib (unsigned terms) { unsigned f1 = 0; // the first term unsigned f2 = 1; // the second term while (terms--) { std::cout<<f1<<std::endl; unsigned f3 = f1 + f2; // the next term f1 = f2; // shift the terms for the next iteration f2 = f3; } }
What does IP3 mean in RF?
IP3 means 3rd-order intermodulation products. When an amplifier is not perfectly linear it distorts the incoming waveform and if signals are input at two frequencies f1 and f2 the basic intermodulation products are at the two frequencies f1±f2. 3rd-order products are f1±2f2 and 2f1±f2. This gives problems because when f1 and f2 are almost equal, there are 3rd-order products that are close to them in frequency and therefore difficult to filter out.
