current is 127.52 microamps. and the current was measured on a 50000 counts digital multimeter on a range with accuracy specification of 0.1% + 5d. what is the resolution and the uncertainty interval associated with this measurement?
Write the mathlab program to plot the modulation index necessary to keep the Vdc constant at 1200v when the input power factor angle is varied from -60 degrees to 60 degrees.
The input to a certain filter is given by Vin(t)=2cos(10000pi*t-15deg) and the steady state output is given by Vout(t)=5cos(10000pi*t+25deg). Determine the (complex) value of the transfer function of the filter for f=5000 Hz.
Calculate the tetrahedral bond angle, the angle between any pair of the four bonds in a diamond lattice. (Hint: represent the four bonds as vectors of equal length. What must the sum of the four vectors equal
Design an active first-order RC low-pass filter (using a 741 op-amp) with a cut-off frequency of 10 kHz and a band-pass gain of 20 dB. Derive the step response and voltage transfer function.
A processor has a 32 MB cache and a 64 bit data bus. What is the minimum width of the address bus needed to access the entire cache
Design a common-emitter BJT amplifier with a gain of -100 (well above 3dB point) and a 3dB point at 100Hz. Assume beta = 100, Ic (quiescent) = 1mA, Vcc=20V. You can omit the output capacitor, but should bypass your emitter resistor.
What are the distinguishing features of the response in the pass-band? What are the distinguishing features of the response in the stop-band? What is an all pass filter?
Calculate the Fourier Transform of f(t) = 5 sinc(-2t/100), and graph the magnitude and phase as a function of f. If the signal of problem 1 is delayed by 0.1 ms. What is the new Fourier Transform.
Determine the output voltage for an op-amp comparator circuit with a non-inverting input reference voltage of + 2 VDC and an inverting input signal of - 1 VDC. The op amp reaches output saturation voltages of ±13 V at the limits.
The following represent soulution of the transmission line disserential equations for some arbitrary function f(u): V(z, t) =60 cos(1000t -5z) -120 pi f (2t +z/100 +12) V i(z, t) = 2 pi f (2t +(z/100) +12) - cos(1000 t -5z) A a) what is the forward p..
Two infinite, thin wires are oriented in the x-direction. One is at the origin, carrying a current of 1A. The second wire is at (0,20cm,0) carrying a current I in the same direction. What current is needed in the second wire to produce 0 magnetic ..
A current of 1600 A exists in a rectangular (0.4-by-16cm) bus bar. The current is due to free electrons moving through the wire at an average velocity of v meters/second. If the concentration of free electrons is 10^29 electrons per cubic meter
