1. Calculate the Fourier Transform of f(t) = 5 sinc(-2t/100), and graph the magnitude and phase as a function of f.
If the signal of problem 1 is delayed by 0.1 ms. What is the new Fourier Transform? Graph it's magnitude and phase as a function of f.
Determine the Fourier transform of exp(-.003t) cos(62,831,850t) for t>0 using the modulation property. What is the spectral density at 200 kHz from the carrier frequency?
The output power of the digital transmitter is 0 dBm and the link has a constant attenuation of 50.0 dB. At the input to the receiver, the equivalent AWGN noise power is – 70 dBm. Assume implementation margin is 0 dB when calculating BER in ..
At what temperature do hydrogen molecules, H2, have the same rms speed as nitrogen molecules, N2, at 455C. At what temperature do hydrogen molecules have the same average kinetic energy.
Selecting a manufaturer from the us and observing wether its annual revenues are more than one billion or not when it is known that 30% of all manufacturers have annual revenues totaling more than one billion dollars.
Maximum Amount of Channels A Link Can Carry, A microwave radio link operates over a bandwidth of 400 MHz at C band. The link carries a number of channels of data using FDMA.
The dielectric materials used in real capacitors are not perfect insulators. A resistance called a leakage resistance in parallel with the capacitance can model this imperfection. A 150-F capacitor is initially charged to 100 V.
Consider variable threshold CMOS fabricated in 0.25-mm technology with tox = 7 nm. The n-MOSFETs and the p-MOSFETs have 2 x 10^16 cm^-3 channel doping; ±3.3 V is available for active body biasing of the MOSFETs.
The power factor of a load connected to a 120-V 60-Hz source is raised from 0.866 lagging to 0.966 leading by connecting a 110.5-?F capacitor in parallel with the load. Determine the load current I1 and the circuit current IT.
The system uses a 7-cell reuse pattern. If the offered traffic per user is 0.03 Erlangs and the average number of calls per hour per user is 1.5, for an Erlang-C system with a probability of delaying a call being 5%, calculate the traffic load per..
Draw a state diagram for an FSM (Moore machine) with no inputs and three outputs x, y, and z, where xyz should always exhibit the following sequence: 000, 001, 010, 100, repeat. Make 000 as the initial state.
As the ball rises, it gradually loses kinetic energy as its potential energy increases. At the top of its flight, when its vertical speed goes to zero, all of the kinetic energy has been converted into potential energy.
A sinusoidal voltage has a maximum value of 100V, and the value is 10V at t=0. The period is T=1ms. Determine v(t)
