The exponential Fourier series coecients for a signalx(t) are: ak= { 1.57 when k=0, 0 when k is even and k doesnt equal 0, ((-1)(k-1)/2)/k when k is odd}Determine the following:(a) Plot the spectrum of the Fourier series.(b) Determine the trigonometric Fourier series coefficients for the first 6 harmonics.(c) Determine the total power of x(t) for the first 6 harmonics(d) How much of the total power of x(t) is in the DC harmonic (i.e. k=0)
An AC synchronous motor operates at 1200 rpm on a 60 hz, 240 Vrms supply. The supply is changed to 50 hz, 240 Vrms, What is the mechanical rotational velocity when the motor reaches steady state
A mass "m = 2 kg" is connected to a spring with spring constant "k= 5 N/m " on a frictionless table oscillation only in 1-D (x direction) . The equation of motion for the mass is given by the equation m (d^2 x(t)/ dt^2) = -kx(t) .
A Gaussian random process having a mean value of 2 and a variance of 4 is passed through an ideal half-wave rectifier. a) Let Xp (t) represent the random process at the output of the half-wave rectifier
Gaussian weighting following ideal, unweighted equalization is used to reduce time sidelobes seen with a 250-MHz chirp-pulse-compression radar. Rectangular chirp pulses are transmitted. (a) What is the half-power compressed-pulse
A U manometer reads 20 cm air as operating fluid and a given manometric fluid. A single branch closed tube reads 35 cm connected to point 1. If P2 = 1.2 ATM calculate the pressure in point 1 and the density of the manometric fluid.
During the cyber security activity conducted in class by Renee Etoty, you were asked to identify systems that were conducting or experiencing cyber attacks. You will use the data provided during this activity to develop a program to display.
Determine the frequency response of this receptor to stretching. There are devices that can apply sinusoidal stretch to a small segment of tissue.
Compute the amount of time required to deliver 10 frames to the receiver with stop-and-wait flow control. Assume that all frames and ACKs are received correctly.
A capacitor in an RC circuit with R = 5.00 ohm and C = 6.00 mF is being charged. What is the time required for the capacitor voltage to reach 86.5 percent of its steady-state value
Assume that in addition to the sine-wave signal you have a dc reference voltage of 1.5 V available. Sketch the output signal waveform.
An internet access provider (IAP) owns two servers. Each server has a 50% chance of being "down" independently of the other. Fortunately, only one server is necessary to allow the IAP to provide service to its customers
