Suppose you are to construct a logic circuit with inputs {A,B,C} and output {F} The logic is such that "F" is asserted only when "A" or "B" are asserted and "C" is not. First draw and complete the truth table , and then use it to construct a canonical sum of products (SOP) expression of the output "F".
A signal x[n] is formed by sampling a signal x(t) = -4sin(200*pi*t) at a sampling rate of 400Hz. Graph x[n] over 10 fundamental periods versus discrete time. Then do the same for the sampling frequencies of 60 and 200Hz.
Assuming no feedback to the adversary until each attempt has been completed, what is the expected time to discover the correct password?
an Armstrong indirect FM modulator to generate an FM carrier with a carrier frequency of 96 MHz and deviation of f=20 KHz. A narrowband FM generator with Fc=200 KHz and adjustable deviation f in range of 9 to 10 Hz is available.
Design a counter that will execute the numerical sequence 0, 2, 4, 6,repetitively. Unwanted states should be directed into wanted states that give the simplest logic functions. - Identify the number of required JK D-FLIP FLOP;
Assume a CDMA system has only 4 walsh codes. If the mobile is assigned W4 and receives a data stream of 11011010, what is the output?
construct a vertical line on your I versus V graph at the point V=5V. this line will intersect each of the sloping lines at two separate points. explain the significance of these intersections.
Control Systems- PID Controller, Which one of the following statements regarding the operation of a PID controller is definately false?
Consider a permanent-magnet dc-motor with the following parameters: Ra=0.35Ohms, La=1.5mH, Ke=0.5V/(rad/s), Kt=0.5Nm/A, and Jm=0.02kgm^2. The rated torque is 4Nm. This motor is supplies by a switch-mode dc-dc converter
A wave propagates 50m through a dielectric of region 1. Region 1 is lossy. Here, f= 0.6 Np/m. At an interface to region 2, the reflection coefficient is r =0.2+j0.5. The wave then propagates 50m back into region 1 from where it originated.

The continuous-time counterpart to the N-point discrete-time MA filter is the I-interval continuous-time MA filter given by the input/output relationship y(t)=(1/I)*Integral of x(lamda) delta lambda where the bounds are from t-I
A chopper is used to control the power flow from a dc source voltage of 125-V to a battery whose voltage is 240-V. The power transferred is 60 kW. Determine the duty cycle and the average input current.
