So a linear amplifier amplifies the signal and the noise powers by the same gain factor. And on top of that, the amplifier adds in its own noise. So the signal to noise ratio is always lower.
And we know that Higher SNR ---> lower bit error rate.
lower SNR ---> higher bit error rate.
So why is a linear amplifier used in various communication systems and computing systems?
