Create a non-inverting op amp circuit to obtain Vout = 12 V if R2 (RF) = 1100k ? and Vin =1V . Open up the attributes window of the op amp (click on the op amp symbol) and verify that VPOS = +15V and VNEG = -15V. Do not change any other attributes or parameters.
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?
A Si PIN photodiode has an i-Si layer of width 20 µm. The p+ layer on the illumination side is very thin (0.1µm). The PIN is reverse biased by a voltage of 100 V and then illuminated with a very short optical pulse of wavelength 900 nm.
The dielectric materials used in real capacitors are not perfect insulators. A resistance called a leakage resistance in parallel with the capacitance can model this imperfection. A 170-F capacitor is initially charged to 100 V
Sketch a time diagram similar to Figure 3.22 illustrating what happens when a frame gets lost between the sender and the receiver. It should be clear from your diagram how the protocol handles this situation.
Determining how to use the function fft to find the DFT coefficients X[k] of x[n] in Matlab. Also, how would you plot the magnitude of X[k] in Matlab?
A circuit must detect a 01 sequence. The sequence sets z = 1, which is reset only by a 00 sequence. For all other cases, z = 0. For example, for input sequence as follows, the corresponding output sequence would be: x = 010100100
b) Calculate the armature current at start c) The motor is now used as a generator. Calculate the speed of the machine if the armature current is 80A and there is a 230V at the motor's terminals. Assume a constant flux.
Computer security is not an issue for organizations alone. Anyone whose personal computer is connected to a network or the Internet faces a potential risk of attack. Identify all the potential security threats on a personal computer.
Hand calculate the expression for the voltage and current of the capacitor and plot these equations by using MATLAB and calculate the time constants of each circuit and point out this time constants at your voltage graphs.
A temperature sensor has a static transfer function of 0.15 mV/C° and a time constant of 3.3 s. If a step change of 22° to 50° C is applied at t=0, find the output voltage at 0.5 s from t=0s to t=10s
For evaporation from a point source, derive the ratio between the film thickness, d and the maximum thickness, d0 on a substrate of radius, r. What is the ratio for a surface source
Design a combinational circuit with four inputs, x,y,w, and z, and four outputs: A, B, C, and D. When the binary input value in decimal is 3,8,12 or 15, the binary output value is one less than the input value, otherwise it is one greater than the..
