Hi Guys,
Can anyone help me with the intuitive understanding of the friis formula?
I'm not able to contemplate the fact that when you put LNA in the front-end of a circuit, overall noise figure is less.
The same hardware, you put it after a few circuitry, the noise figure goes up.
How can the same component cause so much change in noise characteristics of a system when you change its position?
Thanks,
Srini
