1. Find the velocity with which the group of two frequencies 2400 MHz and 2500 MHz travels in a parallel-plate waveguide of dimension a = 2.5 cm and having a perfect dielectric of
2. For a narrow-band amplitude modulated signal having the carrier frequency 5000 MHz propagating in an air dielectric parallel-plate waveguide of dimension a = 5cm, find the velocity with which the modulation envelope travels.
Design the simplest circuit that has three inputs x1,x2, x3, which produces an output value of 1whenever two or more of the input variables have the value 1;otherwise, the output has to be 0.
Design a linear broadside array to have nulls along the directions θ = 50°,130°, and 0° , namely find the number of elements , and the relative currents , find the beamwidth to nulls and the side lobe level .
A tractor-trailer truck driver friend often delivers to companies that do not have a fork truck or loading dock. She wants to install a lift-gate on her trailer so she can load and unload her truck without a fork truck.
Derive the solution (fields and cutoff frequency) for the lowest order TE mode of this structure. Assume the metal plates are infinitely wide. Can a TEM wave propagate on this structure
A wind turbine with a gearbox ratio of 200 produces electric energy when the generator speed is at least 910 rpm. The length of each blade is 5m. The turbine has a variable tip speed ratio (TSR). At a wind speed of 10m/s, compute the minimum TSR o..
An alarm is powered by 120 VAC, and the on/off state of the alarm is controlled by an EM relay. Design the interface between a computer output port and the EM relay. The dropout voltage is 3.5 V, and the coil current needs
The boards have a weight of 40 lb, centered G. Determine the smallest angle Theta required for the man to support these boards, neglecting the man's weight and the friction between his shoes and the floor.
Find two renewable energy application where ac/dc converters are used. Explain qualitatively the role of the converter in the application
construct a block diagram and an ASMD chart for a digital systemthat counts the number of people in a room. The one doorthrough which people enter the room has a photocell that changers asignal x from 1 to 0 when the light interrupted.
The converter canreceive signals from 0 V to 5.0V. Design the electronic processorthat must be connected between the sensor´s output and thecomputer´s converter A/D input; so that maximum sensibility is obtained. Justify each single proposal you m..
An ideal C/D converter is followed by a discrete-time LPF which is followed by an ideal D/C converter. The sampling rate is 8000 samples per second. The input analog signal is bandlimited to 3900 Hz. The overall frequency response is required to s..
Show that aliasing will occur if the signal y(t) = e^-t(sin)(2t) is sampled with T=0.2 by finding the z transform of the sampled sequence and then finding the inverse z transform.
