An NRZ-L signal is passed through a filter with r = 0.5 and thenthen modulated onto a carrier. The data rate is 2400 bps Evaluate the bandwidth for ASK and FSK. For FSK assume that the twofrequencies used are 50kHz and 55kHZ.
If a plane has intercepts at 2a, 3a, and 4a along the three Cartesian coordinates, where a is the lattice constant, find the Miller indices of the planes.
Every 64 cycles, the circuit outputs the average ofthe past 64 input V values, then in the next cycle begins a new calculation (in other words, its behavior repeats). During the cycles when the circuit is not outputting the average, itshould outpu..
Prove the validity of the simple rule for finding 2's complement of a number. Recall that the rule states that scanning a number from right to left, all 0s and the first 1 are copied; then all remaining bits are complemented.
Calculate the energy required to change the arrival time of a near earth object of mass 10,000 MT by a distance equal to the diameter of Earth using laser ablation. Assume an ejection velocity of the material at 10,000 m/sec.
A 120-V source is to be connected to a load by two copper wires. The load is located 500 feet from the source. The maximum voltage drop due to the wire resistance is 10 V, which makes the minimum load voltage 110 V.
If the EM wave of 10 kW transmitted is hitting a truly reflecting building at 20o and 5m from normal, the coefficient of reflection is r=0.5, at which location the reflected ray is max and its power density at 5m in that direction
Consider an air compressor operating steadily. How would you compare the volumetric flow rates of the air at the compressor inlet and outlet. Will the temperature of air rise as it is compressed by an adiabatic compressor.
It is required to design an equivalent analog filter using a digital filter and other appropriate components. Thesampling frequency is fsamp= 20 kHz and the attenuation (α)specifications of the filter are as follows: α > 42 dB for 0 4000 Hz.
Explain an engineering solution for the BP Oil Spill in the Gulf of Mexico. Discuss the impact of the above engineering solution in an environmental context. Do not discuss the environmental impact of the BP Oil Spill.
use series to approximate values of functions. Therefore it is important that we know for which values of x the series will provide good approximations of the given function. Based on the graph can we use the MacLaurin series expansion to approxim..
A speeder is pulling directly away and increasing his distance from a police car that is moving at 25.1 m/s with respect to the ground. The radar gun in the police car emits an electromagnetic wave with a frequency of 7.16E+9 Hz.
Inputs to the register include (i) inputs to the flip-flops, (ii) a clock signal, (ii) a signal to control the transfer and any other signal you might need to accomplish the task Note that register A needs feedback to maintain a copy of the transf..
