An antenna with TAR = 160 K is connected to a receiver by means of a waveguide that has a physical temperature of 290 K and a loss of 2 dB. The receiver has a noise bandwidth of 1 MHz, an effective input-noise temperature of 800 K, and a gain of 120 dB from its antenna input to its IF output. Using MATLAB find
(a) The system noise temperature at the input of the receiver.
(b) The overall noise figure.
(c) The available noise power at the IF output.
A hollow aluminum sphere, with an electrical heater in the center, is used in tests to determine the thermal conductivity of insulating materials.
A -6-nC point charge is located at the center of a conducting spherical shell. The shell has an inner radius of 2 m, an outer radius of 4 m, and a charge of +7 nC. (Let the radially outward direction be positive.)
Determine the ideal impulse response hd [n] to which the Kaiser window should be applied
Find out the voltage that must be applied to the high voltage winding in order to provide rated voltage at the load under full-load conditions at 0.80 lagging power factor.
Plot the torque-speed characteristic for this motor.
A 460-V, three-phase,60-Hz system supplies power to a 10-kVA, delta-connected resistor load; a 50-kVA, 0.86 power factor induction motor, and a wye-connected synchronous motor that is operating at 0.62 power factor leading
Write a short technical report on Frequency Division Multiplexing
Calculate the drain current in an NMOS transistor for VGS = 0, 1V, 2V, and 3V, with VDS = 0.25V, ifW = 5μm, L = 0.5μm, VTN = 0.80V, and Kn' = 200μA/V2. What is the value of Kn
Find the maximum torque on an orbiting charged particle if the charge is 1.60E-19C, the circular path has a radius of 0.5E-10m, the angular velocity is 4E16 RAD/S, and B=0.4E-3T.
2) Draw the logic circuit for each of the following. For each gate, determine EVEN or ODD parity and find the output for the given input data: a) 4-input XOR, input data=1001 b) 5-input XOR, input data-10010 c) 6-input XOR, input data=101001 d) 7-..
what is the maximum bandwidth of this network, in bytes/s.
Compact linear actuators are required to compensate for vibration induced by the motion of a robot arm. The dynamic performance of the actuators is very important to ensure they can provide the required high frequency movements when a load is appl..
