A sampled signal consists of the following set of samples {0, 1, 2, 3, 2, 1}. Determine the DTFS representation for this sample set using the orthogonal basis method. Also, express the result in magnitude and phase form.
On any given day, the price of stock XX can do one of three things: jump very high, fall very low, or stay reasonably close to its opening value. You are trying to use Bayes' Law to determine if stock XX is being bought or sold by shareholders
A buck-boost converter works with an input voltage of 12 V and switching frequency 10 kHz. The load resistance of 24 Ω requires doubled input voltage. The inductor and capacitors are 1 mH and 100 μF, respectively.
Examine the amplitude and phase spectrum of lowpass filtered noise (e.g. cutoff frequency 50 Hz, BUTTERWORTH filter 6th order). Do both exhibit stochastic behaviour? Is the filtered noise also "completely non-periodic"?
Write the expression for the vector distance of a point in a rectangular room from one corner of the room, choosing the three edges meeting at that point as the coordinate axes. Describe the vector distance field associated with the points in the ..
design a circuit to limit the output voltage between -5v and+5v. the input is a sinusoidal source with a peak value of 10 v and a frequency of 1KHz.
The following Figure shows a single diagram of three phase, 60-Hz synchronous generator, connected through a transformer and parallel transmission lines to an infinite bus (SMIB). Calculate the critical clearing angle
Devise a minimal-length binary code to represent the state of a phone: on-hook, dial-tone, dialing, busy, connected, disconnected, ringing.
Suppose you toss coins three times. Let X be the event that first of the three coin tosses results in "heads." Let Y be the event that you observe total of 2 "heads." Are X and Y independent events
A magnetic circuit made of radiometal is subjected to a magnetic field strength of 5000 At/m. Using the data given in Fig. 4.16 , determine the relative permeability under this condition.
What continu-ous reverse current flow appears likely to cause permanent failure? If reverse current flows only 10% of the time at the peaks of a cyclic applied voltage, what peak current can be tolerated?
The load requires 2 hp. If the dc-to-ac converter has a power efficiency of 88 percent and the motor has a power efficiency of 80 percent, estimate the current taken from the dc source.
Determine the maximum motor torque at rated voltage and the slip at which it will occur. Also calculate the starting torque.
