A calibrated RTD with α = 0.0041 /?, R = 306.5 Ω at 20?, and P_D = 30 mW/? will be used to measure a critical reaction temperature. Temperature must be measured between 50° and 100? with a resolution of at least 0.1?. Devise a signal-conditioning system that will provide an appropriate digital output to a computer. Specify the requirements on the ADC and appropriate analog signal conditioning to interface to your ADC.
A 35-year old female worker receives an x-ray exposure of 5.2 rad (whole-body) while carrying out emergency procedures in a nuclear accident. Discuss the health risks assumed by this worker as a result of the radiation exposure.
An optical lithographic system has an exposure power of 0.3 mW/cm2. The required exposure energy for a positive photoresist is 140 mJ/cm2 and for a negative photoresist is 9 mJ/cm2. Assuming negligible times for loading and unloading wafers
Design a synchronous counter with a count sequence of all prime numbers between 3 and 15. Give the excitation equations. Map any unused counter states into the state whose output is the largest prime number output by this counter q.
In each of the three phases in a balanced delta- connected load is composed of a 10mF capacitor in parellel with a series-connected 470 ohm resistor and 4mH inductor combination, assume a phase voltage of 400 V at 50 Hz
use GPS and they are useful for many reasons. GPS receivers use signals from more than three satellites so that cheap quartz clocks can be used instead of expensive atomic clocks. The quartz clocks tend to drift up to + or -1 ns/s.
1. Formulate the cost function in terms of autocorrelation values of the time sequence and filter weights 2. Derive Wiener-Hopf equations (in matrix form) 3. Determine the closed form solution for Wiener-Hopf equations (in matrix form)
Calculate the tetrahedral bond angle, the angle between any pair of the four bonds in a diamond lattice. (Hint: represent the four bonds as vectors of equal length. What must the sum of the four vectors equal
A balanceed three-phase load of 15 MA with a lagging load factor of 0.85 is supplied by a 115KV subtransmission line. if the line impedance is 50+j100Ohm per phase, determine the following: (a) The line current of the load
The purpose of this problem is to show you the connection between Fourier series and linear algebra. For simplicity, we will consider a finite basis. All questions will be referred to the following basis B = {1, sin(400t), cos(400t), sin(800t), cos..
In a Zigbee network, Coordinators and Routers can't "sleep", i.e. enter a low-power, inactive mode. Why is this What implications are there because of this on the structure and applications of a Zigbee network
Simplify the following circuit. Line A goes into an INVERTER, then into a NAND Gate, then into an OR Gate, then travels into another NOR Gate.
Use Smith Chart: A 100 Ohm air-coaxial transmission line is measured to have an input impedance of 100 + j100 Ohms. If the system is operated at 100 MHz and is one meter long, what is the terminating load impedance
