What is the common-mode voltage gain of Fig. 15-37? If a common-mode voltage of 20 μV exists on both bases, what is the common-mode output voltage?
Resistors of R1= 10Ω, R2 = 4Ω and R3 = 8Ω are connected up to two batteries (of negligible resistance) as shown. Find the current through each resistor.
Suddenly there is a short-circuit on the electric grid, and the electrical output goes to zero for 2 seconds. Calculate the increase in speed in rpm during this interval. Assume that the shaft-torque remains constant
a. design a half-subtractor circuit with inputs x and y and outputs Diff and B out. the circuit subracts the bits x - y and places thedifference in Diff and the borrow in B out. b. design a full- subtractor circuit with three inputs x,y,B in andtwo..
A wire is bent in the form of a half loop of radius a=10mm and charged with a line charge density pL=10^-9 C/m. Calculate the field intensity at the center of the loop.
A spherical conductor of radius a carrying a charge s, is surrounded by a thin, concentric spherical conductor of radius b carrying a charge gee Find the potential produced by these conductors at all points of space.
A linear-phase FIR filter should be designed with the ideal magnitude response shown in the following figure. The lower cutoff frequency, fL , is 1,200 Hz, and higher cutoff frequency, fH , is 2,200 Hz. Sampling frequency fS = 8,000 Hz.
Discuss how the conclusions from the two experiments described in parts (a) and (b) will differ.
What is the phase response for {h[n]}? That is, what is the phase versus ω of H(e^jω)?
A single phase AC circuit is conected to a 120V, 60Hz. The circuit impedance is Z=8+j6Ω at 60Hz. Calculate the rms phase current, real & reactive power and power factor.
Convert the decimal numbers +37 and +17 to 8-bit hexadecimal numbers, using the signed 2's complement representation. Then perform the following operations: (a) (+37) + (-17), (b) (-37) + (+17), (c) (-37) + (-17).
A series motor runs at 600 rpm when taking 110 amps from a 230 V supply. The resistance of the armature circuit is 0.12 ohms and that of the series winding is 0.03 ohms. Calculate the speed when the current has fallen to 50 amps
A continuous-time signal x(t)=tri((t-1)/2) is sampled at three rates: 10, 2, and 1 Hz. Sketch the resulting sampled signals. Because x(t) is timelimited, its bandwidth is infinite. However, most of its energy is concentrated in a small band.
