For a 64-PSK modulator with an input data rate(fb) equal to 36 Mbps and a carrier frequency of 100 MHz, determine the minimum double-sided Nyquist bandwidth(fN) and the baud. Sketch the output spectrum.
A star-bus hybrid topology consists of a main three branch star toplogy with each branch connecting three stations in a bus topology. This toplogy is changed to a new bus-ring hybrid topology with main five station bus topology.
Explain the following terms; (i) critical radius of insulation. (ii) economic lagging thickness.
Explain what the cumulative probability distribution function indicates in this case. If the rms value is given by 2 sigma, compute the percentage of time that a signal is 12 dB or more below the rms value for a Rayleigh fading signal.
A control system for positioning the head of a floppy disk drive has the closed-loop transfer function T(s)=11.1(s+18) / (s+20)(s^2+4s+10). Plot the poles and zeros of this system and discuss the dominance of the complex poles.
The signal x(t) = 2 - sin(4.5t - pi / 4) + 3 cos (24t + pi / 2) is input into a system with frequency response H(omega). Find the output signal y(t) if: H(omega) = rect(omega/80) H(omega) = 2 - 2rect(omega/8) H(omega) = sin c(omega/20)
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?
A flood control project with a life of 12 years will require an investment of $300,000 and annual maintenance costs of $25,000. The project will provide no benefits for the first two years but will save $40,000 per year in flood damage
a) Determine the self inductance of coil 1, L11 b) Determine the self inductance of coil 2 L22 c) Determine the mutual inductance between the two coils, L12 or L21
A y polarized UPW motion in + x direction in free space has a maximum value of 20 (V/m) at a point x=1.5 (m) with the next adjacent minimum at x=2.75 (m) at time t=0 Obtain the wavelength and the frequency of the wave.
An OpAMP has a GBWP of 100MHz and a slew rate of 10V/us and AVoc = 160dB at DC. Assume VCC = +/- 15 Volts. a. If the opamp is configured as a non inverting amplifier with voltage gain of 50.
Let the component at Omega(C) = 2pi* 3000 be the corrupting signal. Design an appropriate lter to lter out this component of the input. You can use fir1 command for this. Plot the frequency response of this lter.
