A light source generates 10^17 electron hole pairs per cm^3 persecond in an n-type sample doped ND = 10^16 cm^-3 and the average minority carrier lifetime is 10^-5 seconds. Is this Low level injection.
Assume that in addition to the sine-wave signal you have a dc reference voltage of 1.5 V available. Sketch the output signal waveform.
Consider the logic function f(a,b,c) = abc + ab'c + a'bc + a'b'c + a'bc'. (a) Draw the logic circuit for the function f given above. (b) Let the cost of a logic circuit be the total number of gates plus the total number of inputs to all gates
The radio station 98.5FM has a bad power amplifier such that the received signal at any car radio is actually: x(t) = y(t) + y2(t) where y(t) is the FM signal at the assigned carrier frequency. Assuming your radio has unlimited spectral range
Write an assembly program to calculate sum of number10 through 25
a) Identify the geometric shape that is formed by plotting the above equation. b) Draw the geometric shape defined by the above equation. c) What is the centerand radius of the shape defined by the above equation
a single phase 100 kVA, 1000/100 V transformer gives the following test results: Open Circuit test: 100V, 6.0 A and 400 W Short Circuit test: 50V, 100A and 1800W At what load will maximum efficiency occur
On a breadboards, hook up an IR LED to provide an infrared light source for signaling the phototransistor as shown in Figure 2 below. Use a pushbutton switch to turn the IR LED on and off.
From a large lot of new tires, n tires are to be sampled by a potential buyer, and the number of defectives X is to be observed. If at least one defective is observed in the sample of n tires, the entire lot is to be rejected by the potential buye..
A glass tube with a cross-sectional area of 9^-2 m^2 contains an ionizd gas. The densities are 10^15 positive ions/m^ and 10^11 free electrons/m^3. Under the influence of an applied voltage, the postive ions are moving.
PLL can be used to demodulate an FM signal. If you are tuned to an FM station at a frequency of 101.1 MHz, the free-running frequency of the VCO must be set to what frequency
1) A 1.5H inductor has a constant current of 2.5A. a) find the energy that it holds b) what is its voltage c) what is its energy after its current drops to zero and stays zero What power is dissipated when a 20 olhm resistor is connected to it
A constant magnetic field passes through a single rectangular loop whose dimensions are 0.35 m × 0.55 m. The magnetic field has a magnitude of 2.1 T and is inclined at an angle of 65° with respect to the normal to the plane of the loop.
