1. Find the 4-bit binary-reflected Gray code values for the numbers 0-15.
2. Design a Gray-coded counter in which only one bit changes on each cycle.
3. Adapt the priority encoder logic of to produce three 1-hot outputs corresponding to the first three 1s in an input string.
Design a low cost white LED based emergency light that turns on when the main supply fails, and turns off when the main supply resumes. The circuit must have its own battery charger. When the battery is fully charged, charging stops automatically.
Why is it that the hypothetical but illustrative energy cost is smaller in this problem than the one in Example 2.8?
What is the polarization of this antenna?
Determine the normalized impedance at λ/8 from the load if (a) its normalized impedance is 2 +j, (b) its normalized admittance is 0.2 - j0.5, (c) the reflection coefficient at load is0.3 + j0.4.
Implement the following equation using two operational amplifiers V0 = -5V1 + 2V2 - 10V3. Use minimum value of resistance as 10 kΩ
A motor with an efficiency of 76% supplies 20 hp to a load.It's power factor is 0.6 (lagging). A voltage of 440 VAC (RMS), 60Hz is applied to the motor. a. What is the real power applied to the motor in Watts
An iron core of cross-sectional area 200 square mm and length 320mm is evenly wound with a coil of 100 turns. When a current of 0.35A flows in the coil, a magnetic flux density of 0.12T is set up in the iron core.
A star-bus hybrid topology consists of a main three branch star toplogy with each branch connecting three stations in a bus topology. This toplogy is changed to a new bus-ring hybrid topology with main five station bus topology.
Efficiency in a power transformer is 98.6 percent when loaded such that its core losses equal the copper losses. Calculate the per unit resistance of this transformer.
The DC shunt motor is running at full load with a supply voltage of 440 V and a supply current of 70 A. The rotation speed in full load is 1000 rpm, the field resistance is 200 Ohm and the armature resistance is 0.2 Ohm.
Write down an expression for the pdf of Z.
