B)No


2Does PSD estimation of output of a filter follow similar mathematical relation for both deterministic and noise input?
A)Yes
B)No


3Is it true that power of sum of two noise waveforms is equal to sum of individual powers?
A)Yes
B)No


4Can it be said that thermal noise and shot noise are essentially white noise?
A)Yes
B)No


5Is it true that quadrature components representation helps in addressing narrowband noise?
A)Yes
B)No


6Time derivative of a Gaussian noise does not show Gaussian distribution. Is that correct?
A)Yes
