Determine the maximum bit rate for an FSK signal with a mark frequency of 48Khz, a space frequency of 52Khz, and an available bandwidth of 10kHz.
Suppose that without a 1k-ohm load an amplifier's output voltage is 5Vpp but when the 1k-ohm load is attached, it drops to 3Vpp. What is the output impedance of the amplifier
State the main requirements of a protection CT and an instrument CT - If the setting is 20% and there is saturation of 50% at 20 x current setting, specify a suitable CT.
What is the primary source of distortion with a Class B amplifier. What are some ways the distortion can be minimized and discuss the tradeoffs that exist when implementing these distortion minimizing methods.
Discuss why it is that for a discharging capacitor, the discharge current is in the direction opposite from the charging current. Explain why capacitive reactance is measured in ohms. Also, state two differences between capacitance and capacitive r..
A mealy sequential circuit has one input (x) and one output (z). z can be 1 when the fourth, eighth, twelfth, etc. inputs are present, and z=1 if and only if the most recent input combined with the preceding three inputs was not BCD encoding of a ..
cathodes tied to 10v and ground respectively. The voltage at the anodes is 0.1v. The diodes conduct 1mA at 0.7v.find by what factor the reverse leakage current of the diodes exceed Is.
Consider the mapping of the unit circle (i.e., z = 1ejω, -π ≤ ω
The spring of the pressure gauge shown in the figure below has a force constant of 1385 N/m, and the piston has a radius of 1.00 cm. As the gauge is lowered into water, what change in depth causes the piston to move in by 0.750 cm
The input impedance of a JFET used in COMMON SOURCE configuration, is defined by two considerations: The JFET itself has a VERY HIGH INPUT IMPEDANCE, because the input is the GATE to SOURCE junction that is REVERSE biased
If a plane has intercepts at 2a, 3a, and 4a along the three Cartesian coordinates, where a is the lattice constant, find the Miller indices of the planes.
It starts from rest at the origin. Show that it moves in a cycloidal path and drift velocity or the velocity of the center of the rolling circle along the z axis. If the electric field is 10^4 volts/cm, and the magnetic field 10^4 gausses. find th..
Find the sketch the convolution of the given pairs of functions. You can use either the integration or the graphical method for convolution. x(t) = 2e-3t sin(2t) u(t) h(t) = u(t) + 4d(t-2) find y(t) = x(t) * h(t)
