A special coil of copper wire is embedded to act as atemperature sensor to measure the temperature rise inside amachine. At room temperature of 30oC, the coilresistance is 150 ohms. After several hours of operation, the resistance has increased to 170 ohms. Determine the temperaturerise and the final temperature of the machine.
Distortion per data symbol is negligible and the time variation during a symbol period is negligible - what is the appropriate range of the symbol duration in this communication system?
A house at 42 degree north latitude has a roof that faces due south, and is elevated to an angle of 23 degree. A solar panel is mounted to the roof. what is the angle of incidence between the sun and the array at 10 am on May 5th
1- Find the signal power at the input to the receiver amplifier. 2- Find the noise powre spectrum at the input to the receiver amplifier. 3- Find the signal-to-noise ratio at the receiver amplifier output.
Describe and explain drift current and diffusion current in a PN junction in thermal equilibrium. What causes each In which directions are the electrons, holes, electron current, and hole current flowing for each effect
construct a block diagram and an ASMD chart for a digital systemthat counts the number of people in a room. The one doorthrough which people enter the room has a photocell that changers asignal x from 1 to 0 when the light interrupted.
Consider a Si phtodiode that is designed for operation at 900 nm. GIven a choice of two possible AR coatings, SiO2 with a refractive ndex of 1.4 and TiO2 with a refractive index of 2.3, which would you use and what would be the thickness of the AR..
A 600 V, dc shunt motor has armature and field resistance of 15 ohms and 600 ohms respectively. When the motor runs unloaded, the ine current is 3 A, and the speed is 1000rpm. Calculate the developed torque at a full load armature current of 50 A.
A rectagular waveform has a 50% duty cycle (hight for 1/2 a cycle and low for 1/2 a cycle). It goes between two voltage levels of -3 V (low) and +8 V (high), and has a period of 100 μs. determine the average voltage of this waveform and the RMS vol..
What is the basic of AC circuits What is the way to understand Impedance and application of the laws of Kirchoff, Nodal, Ohm etc on AC Circuits
The mass spectrometer measurement section is a region of uniform magnetic field B= ˆxBms for z > 0. Ions enter the magnetic field (which exists for z > 0) at the origin with a known velocity +ˆz vz.
In a swamped common-emitter BJT amplifier, as shown below, if Vcc = 12 V, R1 = 8.2 k , R2 = 10 k , Rc = 500 , RE = 1 k , VBE = 0.7 V, and = 100, what is the transistor's emitter current
Assume that your application has 600 data reads for each 4000 instructions. For the same number of instruction the application has 400 data writes. The cache used has an instruction miss rate of 0.6% and a data cache miss rate of 6%.
