Determine the impulse response of the following IIR system:

y[n] + y[n - 1] = x[n] - 2x * [n - 1]

3 phase induction motor having 5 poles of 50 hertz frequency

The y-coordinate of a particle in curvilinear motion is given by y = 4t ^ 3 - 3t where y is in inches and t is in seconds. Also, the particle has an acceleration in the x-direction given by a x =12t in./sec^ 2 If the ve locity of the particle in the x-direction is 4 in./sec when t = 0 , calculate the magnitudes of the velocity v and acceleration a of the particle when t = 1 sec. Construct v and a in your solution.

Determine the impulse response of the following IIR system:

y[n] + y[n - 1] = x[n] - 2x * [n - 1]

Determine the impulse response h of the following FIR system:

y[n] = x[n] + 1/2 x[n - 1] + 2x [n - 2] + 4x [n - 3] - x[n - 5]
