In transmission system, noise process N(t) having powerdensity
S.(0) = [(P)/(P + w*)], where P >0 is a constant is mixed with a single A cos(1)
(a) the average signal-to-noise ratio
(b) the value of P such that SNR is maximum,
What is the effect of choosing this value of P?
Signal to noise ratio (SNR) is the ratio of signal to noise. Higher ratio means more signal than noise which is desirable properties.
For more SNR, P signal should me more. Both P signal and P noise should be measured in same units.
