Describe the operation of the series RC circuit. The discussion must address phase angle relationships of current and voltage. The answer must include the effect of source frequency on the voltage drops across the resistor and the capacitor at very low and very high frequency values
A three-phase transmission line having a reactance of 120 ohms per phase is connected to a wye-connected load whose resistance is 160 ohms per phase. If the supply volatge is 70kV line-to-line, calculate a) The line-to-neutral voltage per phase.
Design an EKG amplifier interface to a 6811/6812. The biopotential is a ±5-mV signal measured between the left and right arms using silver-silver chloride electrodes. A third electrode is placed in the right leg and is used as a reference.
Let x(t) and y(t) be two real, periodic signals that are orthogonal to each other. Show that the power of the sum of the signals (i.e., x(t) + y(t)) is equal to the sum of the individual powers (i.e., Px + Py).
An abrupt p-n junction has a doping concentration of 1015, 1016, or 1017 cm-3 on the lightly doped n-side and of 1019 cm-3 on the heavily doped p-side. Obtain series of curves of 1/C2 versus V, where V ranges from -4 to 0V in steps of 0.5V.
Show that for wires of identical dimensions but made of different materials, such as copper and aluminum, the resistance is proportional to the resistivity of the material. the resistance of a certain copper wire is 1.5.
Give the zero-input or natural response yn(t), in terms of constants K, and K2. Give the general form of the forced response y phi (t), in terms of a constant beta. Find beta and give the exact forced response y phi (t).
The angle of departure is defined as 180 degrees plus the phase angle of GH computed at the complex pole, but ignoring the contribution of that particular pole.
a. Draw a block diagram of a closed-loop control system. b. Use the block diagram to describe how the system works. c. What is the advantage of this system over an open-loop system
The charge leaving the positive reference terminal of a voltage source is q(t)= [6sin120pi*t - 8cos120pi*t]mC the voltage source value is v(t)= 160cos120pi*t V. A) Determine the power supplied by the voltage source at t=0
If the data stream is transmitted using a bandwidth of 64 kHz in an ordinary system (without spread spectrum), what is the SNR that could be tolerated without experiencing significant errors
The voltage of a resistor is calculate by the Ohm`s Law: V = R I. write a program that will input resistance R, current I for several resistors, and will calculate and display the voltage for each resistor.
Analysing an RF splitter and power levels, A splitter is a device that has a single input and several outputs. It is used to send a signal to several different locations
