A meta dyne with a uniform air gap is driven at constant speed with a constant dc voltage applied to the q brushes the stator is unexcited. Determine the current in the two circuit and the voltage between the q brushes. what driving torque will be required.
Examining frequency to time domain signals, A spectrum analyzer is connected to an unknown signal. The spectrum analyzer displays the power level of signals in dBm vertically and frequency horizontally. The spectrum of the unknown signal creates t..
Write a short technical report on Frequency Division Multiplexing
What are the techniques used to make feedback system stable? Explain and draw the frequency response of a 1-pole feedback amplifier.
how does your answer change if the bubble is elongated in the direction of the electric field and sphere and the dielectric shell are placed in an initially uniform electric field E 0 in the z direction.
Finding values of a composite discrete time signal, A discrete time signal x(n) = x(n-1) + x(n-3) with initial conditions x(0) = 0, x(1) = 1 and x(2) = 2 is examined and the first 51
What is correct symbol rate (pulse rate) for this link? What is the bit rate with BPSK modulation? What is the bit rate with QPSK modulation?
In a typical mobile communications base station (or cell site), a radio frequency (RF) signal is amplified in the base station and then sent (over cable) to the antennas at the top of the tower.
What is the symbol rate and what is the bandwidth occupied by the 16-QAM signal? The link must maintain a BER no higher than 10^-6. What is the minimum CNR in the receiver to meet this requirement?
Describe in you own words how a modem works and what steps the data goes through to be sent from one terminal to another via modem.
a plane wave is obliquely incident onto the planar interface between mismatched, lossless, nonmagnetic, uniform media, yet undergoes no reflection. If incidence is at 54 degrees to the normal, at what angle to the normal does the transmitted wave ..
