Your boss asks you to contruct a temperature sensorfor measuring the ambient temp outside (-30degreee celcius<= T<= 40 deg. c). You decide to base operation on the change inresistance accociated with a bar shaped piece of SI.(a) indicate doping and dimensions of your sensor(b) derive an expression for the sensitivity (dR/dT inΩ/deg celcius) of sensor over operating temp range. Is itpreferable to use low or high dopings? explain.(c) What are the upper and lower temp limits of op(approx)?explain.(d) Plot R vs. T of sensor over required temp range ofoperation.
Determine the 8-bit sign-and-magnitude, 1's complement, and 2's complement representations for each of the following decimal numbers: +36, -84. (Note: Be sure to represent +36 as a positive number and -84 as a negative number.)
A particular inverting amplifier with nominal gain of -100 V/V uses an imperfect op amp in conjunction with 100-k ohm and 10-M ohm resistors. The output voltage is found to be +9.31 V when measured with the input open and +9.09 V with the input gro..
The difference in voltage (Bat A - Bat B) should be displayed on a +5V - 0 -5V meter. Each volt on the meter display should correspond to 10 mV of battery difference. Include your choice for all components and power supply voltages.
In a unity feedback system, the open-loop transfer function is of the form Gol(s) = k/(1+s/ωp). Calculate the bandwidth of the closed-loop transfer function. How does the bandwidth depend on K and ωp
What fixed point unsigned representation, with how many bits and how many bits to the left of the binary point, should we use if we need to represent numbers in the range 0 - 100 with a resolution of .001 or better
An industrial load consumes 88 kW at a power factor of 0.707 lagging from a 480 Vrms line. The transmission line resistance (Rline) from the power company's transformer to the plant is 0.08 Ohms.
The transfer function of a system is formulated as H(f)=2f^2+i3f+2. Calculate the output signal for the input signal below which was applied to this system Vin(t)= 5+2cos(20(pi)t+30degrees)+sin(10(pi)t)
For the difference equation below, find the impulse response by first solving without any transforms. Assume sequence is zero-valued for n
Briefly explain your ideal job as electrical engineer? Why did you select this career? What goals do you have in this career? How do you plan to get these goals?
Model the line as an infinite filament of current under dc conditions. Calculate the magnetic field intensity in amperes/meter at the top of the head of a man who is 2 meters tall. Assume the man is standing on the ground directly underneath the l..
Determine the N-point DFT X[n] of the N-point sequence x[n]=sin(ωon), 0≤n≤N-1, for ωo ≠ 2∏r/N, where r is an integer in the range 0
