Question

Noise, noise figure, microwave theory, Please attempt both, clearly show me all the steps. Please

3. Derive an expression for noise figure for a cascaded amplifier section. What deduction can you make from this equation? . Assuming you have three amplifiers with the following parameters in table Q1; Table Q1 AmplifierNoise Figure (dB)] Gain (dB) 6 20 20 7 7.4 10 Gh3 How would would you arrange these amplifiers in a cascade to minimise the noise figure?
