For the following questions answer them individually
Question 26
For an n-channel MOSFET,if condention parameter $$(k_n)$$ is 0.249 $$mA/V^2$$, gate to source voltage $$V_{QS}$$, is $$2V_{TN}$$, where $$V_{TN} = 0.75V.$$ The current will be
Question 27
If $$\alpha = 0.98, I_{co} = 6 \mu A, \& I_R = 100 \mu A$$ for a transistor, then the value of $$I_C$$ will be
Question 28
A unit step voltage $$2u(t - \theta)$$ is applied in a series RC circuit with $$R = 2Ω, C = 1F$$. Assuming zero initial conditions, find i(t)
Question 29
The autocorrelation of a wide-sense stationary random process is given by $$e^{-2 |r|}.$$ The peak value of the spectral density is
