1)Please common mode gain of an Op-amp. What is the ideal value of a common mode gain should be? Explain your answer. Just give us the basic understanding by defining common mode configuration.
2)find some more information on signal source impedance and it's effect on amplifier. I also don't think signal source has any impact on amplifier gain.
Just a few sentences are needed for each question.
A three-phase Y- connected load is rated at 240 volts with power factor .95 (lagging), if the total apparent power is 240 KVA, compute: a. the phase currents (in polar form). There are 3 values. b. the active and the reactive power of the load at it..
Sketch the appropriate equivalent circuit and phaser diagram and, assuming step-down operation, determine (a) the magnetizing current and the core-loss component of exciting current; (b) the exciting current; (c) the no-load power factor; (d) the ..
Consider a three-phase distribution feeder with line reactance of10 ohm supplying a three-phase Y-connected load of 200 kVA at power factor of 0.85 lagging.
a load taking 24.4a is supplied by aluminum and copper cables connected in parrel.the lenght of the copper and
(a) Draw the equivalent circuit. (b) Determine the ohmic value of the impedances. (c) Calculate the source current in amperes and in percent if the generator operating voltage is 3.8 kV (line-to-line) and a reactance of X=125% is connected in seri..
The electrostatic equivalent circuit of a human being. A person is charged to 20 kV and touches an object having a 50 ? resistance to ground. Determine the maximum current which will flow in the object.
Consider a system for which the output voltage is vout(t) = vin(t) + vin(t - 10^-3). (In other words, the output equals the input plus the input delayed by 1 ms). Given that the input voltage is vin(t) = Vmax*cos(2*pi*f*t),
In n-channel JFET, Ohmic region is separated from Saturation region by VP so called Pich-off voltage or VGS(OFF). What is the value if IDand VGS at this location and how we can calculate the value of VP from ID and VGS
design your circuit using only two, three, and four input NAND gates and inverters. try to minimize the number of gates and inverters required. the variables A, B, C, AND D will be available from toggle switches.
Fins are used to enhance the cooling of an object. Fins are manufactured in a wide variety of shapes and sizes, and for a mass-product, it may be beneficial to optimize the shape of the fin. find the dimensions of the fin that achieve a maximum
A random signal X can be observed only in the presence of independent addictive noise N. The observed quantity is Y = X + N.The joint probability density function of X and Y is f(x,y) = K exp[-(x2 + y2 + 4xy)] all x and y
