Cont. at 0.07.0°. 2011 a) What is the wavelength of the incident light? b) If the screen on which the diffraction pattern is produced is placed 0.8m away from the slit, determine the width of the central maximum.
2. Active Second Order Butterworth Circuit Show that the following circuit has the transfer function shown. Design the circuit such that it has a unity gain and cutoff frequency of 1000 rad/sec and $C = 1\mu F$. Plot the Bode plot in MATLAB and then simulate the frequency response with the AC Sweep tool in Multisim #1/4#3 $H(s) = \frac{1/RC}{s^2 + 1/RC}$ $V_{in} - V^+ = \frac{V^+ - 0}{\frac{R}{R} + \frac{1}{sC}} \approx 0$ $\frac{V_{in} - V^+}{R} = sCV^+$ $V_{in} - V^+ = sRCV^+$ $V_{in} = (1 + sRC)V^+$
For the AC circuit below, the radian frequency is $\omega = 50 \text{ rad/s}$. $V_S = 120V_{RMS}\angle 0^\circ$ (a) Give the complex power of the source (b) Give the power factor
Consider the electronic circuit shown below. The charge of the capacitor obeys the following differential equation: \[ \frac{d^2q}{dt^2} + p \frac{dq}{dt} + q = 0 \] with initial conditions: \( q_0 = 0 \) and \( \frac{dq}{dt} \bigg|_{t=0} = 1.0 \) 2-a) Use the Laplace transformation method to find \( Q(p) \), which is just the Laplace transform of the solution \( q(t) \) of this equation? 2-b) Find the Laplace inverse of \( Q(p) \) to get the solution \( q(t) \).

Q7: write down any of two short notes a) Difference between ARCH and TARCH b) ARMA and ARIMA process c) VAR and SVAR
TCO 8) Tomcat Company is planning to acquire a $250,000 machine to improve manufacturing efficiencies, thereby reducing annual cash operating costs (before taxes) by 80,000 for each of the next five years. The company estimated the weighted average cost of capital (WACC) is 8%. The machine will be depreciated using straight-line method over a five year life with no salvage value. Fritz is subjected to a combined 40% income tax rate. Required. A. What is the estimated net present value (NPV) of the proposed investment B. What is the payback period?
