All students to attempt the following question
An overhead transmission line conductor having a parabolic configuration weighs 1.925 kg/cm2 per metre of the length .The area of X-section of the conductor is 2.2 cm2 and the ultimate strength is 8000kg/cm2. The supports are 600 m apart having 15 m difference of levels.
Calculate the sag from the taller of the two supports which must be allowed so that the factor of safety shall be 5.
Assume that ice load is 1 kg per metre run and there is no wind pressure.
Develop a voltage-to-current converter that satisfies the requirement I = 0.0021Vm. If the op amp saturation voltage is ±12 V and the maximum current delivery is 5 mA, find the maximum load resistance.
Two components of linear distortion produced by transmitting asignal through an LTI (linear time invariant) system: Amplitude distortion - the frequency components of the input signalare transmitted through the system with different amounts of gain..
Consider a p-type semiconductor substrate with Na =10^15 cm^-3. A region of heavily p+ doped material is formed by ion implantation as shown in the sketch below.Derive an expression for the built-in voltage under equilibrium conditions.
Consider the step responses of two different imaging systems, one with a circular aperture of diameter 2ω and the second with a square aperture of width 2ω, with one edge of the aperture parallel with the edge of the step.
The voltage ratings are 4800v rms and 240v rms for the primary and secondary windings, respectively. The transformer is rated to 10KVA. Now we want to use this transformer at 120Hz. Discuss the factors that must be considered in setting ratings ap..
Use rail voltages of +/-15V. Sketch the circuit diagram and the voltage transfer characteristic (Vout vs Vin) Discuss how you chose the values of the components and comment on how accurately you think you can achieve the specification.
Design a finite state machine that has an input (w) and an output(z). The machine is a sequence detector that produces (z =1). when the previous two values of (w) were (00 or 11); otherwise (z = 1). Assume the initial state is unknown past with (z..
The steering wheel has backlash. This means there is a delay between the time the wheel is turned, and the time the car responds. The driver tends to overturn, which leads to instability and lack of control of the car.
An opamp based integrator is measured at 1KHz to have a voltage gain of -100 V/V. At what frequency is its gain reduced to -1V/V. And, what is the integrator time constant
Discuss the flat and segmented memory models and provide an example
a piston cylinder device initially contains steam at 3.5 MPa, superheated by 5 C. steam loses heat to the surrounding and the piston moves down hitting a set of stops at which point the cylinder contains saturated liquid water.
