In a line of sight link , the transmitted power = 1 watt at the frequency of 11 GHz and the transmitting antenna has gain of 1000 , the receiving antenna is 40 Km apart from the transmitting station, find the receiving antenna gain in order to secure a C/N of 30 dB given that the noise power level N=-125.6 dBW , you need to account for a 2 dB cable loss on the receiving side.
A large number, n, of closely spaced turns of fine wire are wound in a single layer upon the surface of a plastic sphere of radius, R, with the planes of each turn perpendicular to the axis of the sphere and completely covering its surface.
A 3-bit binary counter can be implemented with 3 T-flip-flops and some additional logic. Design the counter. Draw the block diagram (gates) and show the Boolean logic the input into each Flip-flop.
A 150-MVA 15/200-kV single-phase power transformer has a 0.018ohm resistance and a 0.075ohm reactance. The magnetizing impedance is j80 per unit. a.) Find the equivalent circuit referred to the low-voltage side of this transformer.
An electron is confined inside a potential well with infinite walls. The width of the of the wells = 5nm. What is the probability of finding a electron within 1nm from either wall if the electron is at: A)the lowest energy level B). the 2nd lowest ..
Consider a communications channel with a passband of 3 kHz to 27.4 kHz. A modem will be connected to this communications channel and the modem will operate with a signaling rate that is 0.56 the maximum allowable signaling rate for this communicat..
There are a number of factors and precautions that need to be considered when developing and introducing new technologies to the marketplace. This is especially the case when this could be a technology without a sustainable known history.
Consider a discrete time LTI system with impulse response given by h[n] = u[n + 2] - 2u[n - 1] + u[n - 4]. A. Determine the transfer function H(z) for this system. B. Determine the z transform Ys(z) of the step response for this discrete time LTI ..
Write the formula for the maximum clock frequency for an n-bit synchronous parallel binary counter. Beyond what value of n is your formula no longer valid. let Ttq denote the propagatoin delay from T to Q in a T flip-flop.
What is the frequency response analysis. Which two parameters are used to determine frequency response. Draw Bode Plot for G(jw) = 10 (jw + 3) / [(jw)(jw + 2)]
The following signals are sampled using a train of impulses with periodicity kT: signal x(t) Is sampled to obtain and signal y(t) Is sampled to obtain yc(t) Determine the range of values for T that allows complete recovery of x(t) from xc(t)
Discuss the operation of a JFET, including the pinch off and gate-source cutoff voltage in your explanation. Discuss how you can tell whether an FET is operating in the ohmic region or the active region.
A control system is needed to control a small shopping center parking lot lighting system and the exterior lighting for the building. The design specifications require that the parking lot lighting and the exterior lighting turn on at dusk automat..
