Given a DSP system in which a sampling rate of 8000 Hertz is used and the antialiasing filter is a second order Butterworth low pass filter with a cutoff frequency of 3.2 KHz determinea. The percentage of aliasing level at cutoff frequencyb. Percentage of aliasing level at 1000 Hertz.
Identify how the existence of interest groups and political parties affect the public opinions of Texans. Is this affect beneficial or hinderances to the prinicipal of local control popular in Texas policy Why
Determine whether the follow signals are period and for those that are find the fundamental period. F: x(t) = cos(t)u(t) G: x(t) = v(t) + v(-t) where v(t) = cos(t)u(t) I: x[n] = cos((1/5)(pi)(n)) * sin((1/3)(pi)(n))
Express the sequence x(n)={1 n=0 , 2 n=1 , 3 n=2 , 0 else} 1- Express the signal as a sum of weighted and shifted unit impulse sequence. 2- Express the signal as a sum of weighted and shifted unit step sequence
A NEMA design B, 3-phase, 60 Hz, Induction motor is rated: 60 HP, 460V, 71A, 93.0% efficiency, NEMA code G, 1180 RPM: A. What is the power factor of the motor B. What is power factor of the motor when operating at 1/2 load
For the grounded gate p-pullup pseudo NMOS circuit shown below assume the load capacitor, CL, is initially discharged, and that the input voltage abruptly drops from Vdd to zero. Derive the equation for the output voltage charging behavior.
Where (in the sequence of subsystems within a communication system) does the line encoder used? Draw a block diagram. Write a sentence or two on what is in the other boxes. What are the two broad parameters associated with an efficient line encoder..
Plot the signal x(n) 0
What is the magnitude of the frequency component at 30 kHz? The square wave is passed through an ideal rectangular low pass filter that completely attenuates all frequencies higher than 35 kHz. Write down an equation for the spectrum at the output ..
An analog signal xa(t), band-limited to 5 Hz, is sampled at a rate of 10 samples per second to give a discrete-time signal x(n) = xa(0.1n). The discrete-time signal x(n) is then filtered with an digital FIR filter, h.
Four frequencies are applied at the input of a non-linear amplifier. Write down all of the frequency components at the output of the non-linear device. Write down only the first three harmonics. Frequencies of 1205Khz, 1200Khz, 1195Khz
Explain and discuss the problems presented by electronic discovery in civil actions and how the law has responded.
