Suppose a bunch of 10-kohm resistors are available in the lab. A powered bread board with DC voltagepower supplies of +15 V and -15 V is available, along with aground post (0 V). Several type 741 op-amps, some switching diodes,and +5 V and -5 V power supplies are also available. Draw acircuit diagram showing how an inverting amplifier with a gain of -1.5 can be constructed with these components only. Use the standard triangle symbol for the op-amp(s), and label the inputsVn and Vp.
PAL12H6 (12 inputs, 6 outputs, AND-OR structure, two output OR's have 4 AND gate inputs and four output OR's have 2 AND gate inputs). NOTE: you need to show only appropriate product terms used for PAL implementation
The electromagnetic wave that delivers a cellular phone call to acar has a magnetic field with an rms value of 1.38E-10 T. The wavepasses perpendicularly through an open window, the area of which is0.244 m2.
With each quadratic polynomial x^2 + ax + b with real coefficients, associate the smaller of its two real zeros. Is this association a function? If this association is not a function, explain why. If this association is a function
The teacher decides that he will not lecture unless at least k of the n students enrolled in class, are present. Each student will independently show up with probability pg if the weather is good, and with pb if the weather is bad.
A 9-V flashlight battery has a rating of 1.8 kWh. If the bulb draws a current of 100mA when lit: determine the following: (a) For how long will the flash light provide illumination
An n-type piece of silicon with a length of .21um and a cross section area of .05x.05 um sustains a voltage difference of 1V. If the doping level is 10^17 cm^-3, Calculate total current flowing through the device at 300K
Suppose the electron concentration in a piece of silicon is equal to N at x=0 and falls linearly to zero at x=L. Find the expression for the diffusion current density. Calculate the current density for N=10^16 cm-3 and L=1 µm.
design a multirange ammeter with ranges of 1-10mA,0-100mA, and 0-1500mA, using a 5mA movement whose internal resistance is 3.8ohms. draw a circuit diagram of the meter.

1. design a simple power factor meter to operate from 230v mains. current range=1 to 10 amps. power factor range : 0.4 to 1 2. what is meant by normal mode rejection an A/D converter has 20ms integration time.
A rectangular loop of wire containing a high resistance voltmeter has corners initially at (a/2, b/2, 0), (-a/2, b/2, 0), (-a/2, -b/2, 0) and (a/2,-b/2, 0). The loop begins to rotate about the x axis at constant angular velocity w.
Create a Verilog module that implements 4 bit full adder-subtractor with overflow detection. You may use Verilog bitwise operators and gate primitives, but no mathematical operators or behavioral Verilog syntax.
