Assume that an AM system operates with an indexof 0.6 and that the message signal is 12 cos (8π) . Compute the efficiency, the detection gain in dB, and the output SNR in decibels relative to the baseband performance PT /N0W. Determine the improvement (in decibels) in the output SNR that results if the modulation index is increased from 0.6 to 0.9.
four loads are connected in series across 110 volts D.C.THE loads fail to operate.a voltmeter connected in succession across each device reads 0 across the first three loads and 110 volts across the fourth load.What circuit fault is indicated at t..
where R is the resistance at temperature T(measured in C), R0 is the resistance at T = 0 C and α is a temperature coefficient. For copper, α = 4 * 10-3 C-1 . At what temperature is the resistance greater than R0 by 1 percent
a) Draw the circuit diagram of a bridge rectifier made from pn junction diodes that will function as a negative ectifier. Show the path of current flow for both positive and negative Vin. b) Plot the Vin-Vout transfer characteristic of the circuitd..
1. draw a pair of concentric circles. the radius of a smaller circle has to be 40% as large as the radius of the other circle. you decide to make the radius of the smaller circle 5". what would be the circumference of the larger circle approximat..
Attenuation of received power with change in transmission frequency and distance between the antennas
Calculate the net work done by the fluid, for an initial volume of 0.05 m3.
a) What would be the value of the parity bits. b) If some of the bits get flipped in transmission and the following bits are received 1101 0101 0001 0010 1010 with the parity bits, can you detect the error. Can you correct it.
1- Find F(s) for = A[ a cos(ßt) + b sin(ßt)] u(t) and plot and the poles and zeros in the S- plane. 2- find f(s) for = 2d(t) +4e^-2t cos(2t) u(t) and plot and the poles and zeros in the S- plane. 3- find f(s) for = 10[3-6t-4e^-2t] u(t) and plot and t..
Specifically, what equations would be helpful to use to determine the AC power to the consumer and the voltage at the generator end of the transmission line? I don't know where to begin.
Design and development department associated with a power generation plant has various issues which require resolving. You are now asked to provide a series of written solutions on the analysis.
Consider the following pilot (or training symbol) based scheme that converts the non-coherent communication into a coherent one by providing receiver CSI. The first symbol of the block is a known symbol and information is sent in the remaining sym..
