Si p-n junctions are often used as temperature sensors.Draw relevant schematic below and calculate the diode voltage if the temperature is raised by deltaT= 20c above the room temp.

Assume the turn-on voltage for the diode equals 660 mV at room temperature while conducting 10uA current.

please show all steps.

Write a literature survey about DC power supply circuit and audio amplifier circuit to preform a speaker?

e) In order to test the functionality of a piezo sensor, we simply connect a LED with a resistance to the piezoelectric sensor. a. (5 pts) Could the LED work if we put pressure to the sensor? b. (10 pts) what is the element that we have to add ( not a rectifier circuit or capacitor )to make sure that the LED will provide light ? why , justify ? can we use aurduino for this task.

Explain the concept of linearity. Why is important this concept in engineering. Explain.

1. For your choice of input voltage, load resistor and the value of the ripple voltage (as percent of Vdc) design a circuit for the half-wave rectifier.
2. Assuming the value of V_on for the diode, calculate theoretically all parameters of the rectifier: Vp, Vdc, Idc, C, Isc, PIV and diode conducting interval.

If you wish to estimate the proportion of engineers who have studied probability theory and you
wish your estimation to be correct within 2% with probability 95% or more, how large the sample
you would take
(a) if you have no idea what the true proportion is, [Ans: 12500]
(b) if you are confident that the true proportion is less than 0.2. [Ans: 8000]

Q: In MATLAB, make time-domain graphs of a Conventional DSB AM signal u(t) = A_c[1 + am(t)]cos(2×π×f_c×t), with A_c = 1, m(t) = cos(2×π×f_m×t), f_c = 1 kHz, f_m = 50 Hz, for four cases of AM modulations: a = 0, a = 0.3, a = 1, a = 1.3. Your graphs should be over four periods of the message (i.e., 0 < t < 4/fm). Include your code in your solution as well as the four graphs.

use matlab

y(t)=10*(cos(2*pi*500*t)+cos(2*pi*1000*t)+ cos(2*pi*1500*t)).

e) Down sample y(t) by a factor of 6. Sketch the Fourier transform with appropriate frequency axis. Check if all frequency components are correct?

Up-sample the time-domain signal obtained in e) by a factor of 6. Use appropriate filter for interpolation. Sketch the Fourier transform of the up-sampled and filtered signal. Does the resulting signal show all frequency components of the original signal y(t)?
