(a) Design an operational amplifier whose output (for a sinusoidalsignal) is equal inmagnitude to its input and leads the input by 450. (b) Given an operational amplifier consisting of R and L in series for Z, and C for Z ‘.If the input is a constant V, find the output vo as a function of time. Assume an infinite open-loop gain
Discretization - How does the size of the differential charge elements influence your results Find E at the point (0, a/2, a), for this study. Devise a good way to represent your data to demonstrate the influence of discretization.
a) Draw the phasor diagram for V1, V2 and V3. b) Find out the value of V1+V2-V3 and draw the phasor diagram for it. c) If the frequency of all signals is 60Hz, then what is the angular position V1 and v2 and v3 at 10th second
Model the line as an infinite filament of current under dc conditions. Calculate the magnetic field intensity in amperes/meter at the top of the head of a man who is 2 meters tall. Assume the man is standing on the ground directly underneath the l..
A 2400-115V transformer has a sinusodial flux expressed by φ=0.113 sin 188.5t. determine the primary and secondary turns.
Your task as an engineer working for this real estate company is to first select a site for the housing venture. You are given that this area in Queens is prone to earthquakes due to seismic faults. The mean detection rate for tremors is 2 per sq...
The furniture store manager rarely finances purchases, but will for Terry "as a special favor." The rate will be 10% per year, and because the desk costs $600, the interest will come to $60 for a one-year loan. Thus, the total price is $660, and T..
Two dc motors are compared. the first one is a 4hp dc motor which draws a current or 0.7A when the field is connected to a 150V source. the second, a 600 hp motor draws a field current of 5A when the field is connected to a 300V dc source.
A six pole, 400 V d.c. motor draws 110 A from the supply. The shunt field resistance is 200 Ohm and the armature resistance is 0.5 Ohm. The armature is wave wound with 600 conductors operates at a speed of 1200 rev/min when supplying full load.
A balanced three-phase 60 Hz source supplies power to a balanced-connected inductive load. The line voltage is 440 V, the line current is 8.2 A, and the power delivered to the load is 5 kW.
In a unity feedback system, the open-loop transfer function is of the form G_ol(s)=k/(1+s/Omega_p) Calculate the bandwidth of the closed-loop transfer function. How does the bandwidth depend on k and Omega_p
An enhancement-type NMOS transistor with Vt=2 V has its source grounded and a 3-V DC source connected to the gate. Determine the operating state if a. vd = 0.5 V b. vd = 1 V c. vd = 5 V
A thermometer, initially at a temperature of 75 degrees Fahrenheit is suddenly immersed into a tank of water with a temperature of 180 degrees Fahrenheit. The time constant of the thermometer is 4 s.
