Choose appropriate values for N0 and T and compute the DFTof the signal e^(-t)u(t). Use two different criteria for determining the effective bandwidth of e^(-t)u(t). Ad the bandwidth, use the frequency at which the amplitude response drops to 1% of its peak value (at w=0). Next use the 99% energy criterion for determine the band width.
For both designs, the supply voltage is nominally 9 V and varies by +/- 1V. For the first design, assume that the availability of supply current is not a problem, and thus operate the diode at 20mA. For the second design, assume that the current f..
a) The input of Hex- to - seven segment decoder is 1010. what will the display show b) A priority encoder has all inputs activated. Which input will be encoded. Why c) how many select input lines are needed for a 128- to - 1 multiplexer
Why is quality a difficult term to define. how can we improve our understanding of quality?
Design a 4 input, 1 output combinational circuit. the input represents a 4-bit number, N = X3X2X1X0, which ranges from 0 to 15. The output, PN is 1 when N represents a Prime Number,PN, otherwise PN is 0
A single-phase, 60-Hz power will be transmitted through the transmission line Each subconductor's radius is 10 cm. There are two configurations, the first one is setting subconductors A and B as a bundle, and C and D as another bundle
A system is needed to measure flow, which continuously cycles between 20 and 30 gal/min with a period of 30 sec. The required output is a voltage varying from -2.5 to +2.5 V for the cycling flow range. The sensor to be used has a transfer function..
a) If the internal resistance of a voltmeter is 100x bigger than the output impedance of a circuit, what is the loading error b) If the internal resistance of an ammeter is 10x smaller than the output impedance of a circuit
Write a simple shell script called mathmagic that takes two arguments in at call time and returns to the stdout the value of the two items entered, the value of the two items added together, the value of the two items subtracted
An unknown semiconductor has a bandgap of 1.1eV and Nc = Nv. It is doped with 10^15 cm-3 donors where the donors fully ionized. Given that EF is 0.25 eV below Ec, calculate the concentration of electrons and holes in the semiconductor at 300 K and..
a 2000kg ship initially at rest in an inertial system is accelerated along a straight line for (3.16E7 seconds) by means of a photon rocket of 300MW power. If this is accomplised using a series of He-Ne lasers with wavelength=633 nm
An 8 bit shift register is configured so that the output of the least significant bit is fed back to the input of the most significant bit. If the register has an initial state of 11010001, what does the shift register contains after three clock p..
In a balanced three-phase system, the abc phase sequence source is wye connected and Van=120
