A differential amplifier circuit is shown below, where the Op amp is TL081, R1=1kW and Rf=10kW. The bode plot (gain curve) is provided (the straight line is the gain curve). According to the TL081 datasheet, the input noise voltage and current of TL08 are 25 nV/ÖHz and 0.01 pA/ÖHz, respectively. Assuming the circuit operates under room temperature, please find:
1) the output voltage Vout;
2) the GBP (gain-bandwidth product) of the Op amp;
3) the bandwidth of the differential amplifier; and
4) the noise voltage at the output of the differential amplifier.
Design a circuit which realizes this filter using Sallen-Key configuration. Find all the values of the circuit elements and determine the DC gain. For sake of easy availability of parts to build the circuit, chose the capacitors needed to be 0.01..
Your new assistant has measured the signal coming from a piece of test equipment, writing v(t) = Vxe(-2+j60)t, where Vx = 8-100V. (a) There is a missing term, what is it and how can you tell it's missing (b) What is the complex frequency of the si..
Why do you think we need both rectangular and polar forms. There still seems to be some confusion about the relationship between R, Xc, OR XI and the phase angle. Take a value for R and a value for XC that is ten times smaller than R and find the..
Design an open-circuited, shunt stub matching network to match a 125 + j20 ohm load to a 700 MHz, 50 ohm generator. Show the lengths of your transmission lines in fractions of a wavelength. Show steps to solution please.
Consider the analog filter H(s)=30000/(s^2+400s+30000) , notice that the filter gain in the passband is unity or 0 dB. You can also use MATLAB command "roots" to check for the poles that are p_1=-100 rad/s, and p_2=-300 rad/s.
Develop a system to help students learn Morse Code. The system will have one input and 26 outputs (one per letter). The user sends in Morse Code pulses on the input, and as characters are completed the appropriate letter is lit up momentarily.
Consider a thin ring of radius a with uniform charge density and total charge Q. The ring is cut in half across the diameter and the two halves superimposed to double the effective charge density.
Determine the system impulse response in time domain and draw its root locus and comment on system stability.

150 kVA, 2400/240 V single-phase transformer has the parameters. (a) Determine the equivalent circuit referred to the high-voltage side. (b) Find the primary voltage and voltage regulation when transformer is operating
A permanent magnet dc motor is delivering zero torque when it runs at 1800 rev/min and has 50 V dc applied to its terminals. The armature resistance is 2.0 ohm. What current will the motor need in order to deliver a torque of 2.0 Nm
In a certain crystalline material the vacancy concentration at 25*C is one-fourth that at 80*C. At what temperature would the vacancy concentration be 3 times that at 80*C 2. Suppose one attempts to add a small amount of Ni to Cu in an effort to cr..
