Invariant (LTI) system unit impulse response of linear structure as h[n] = u[n - 3] being taken. This system determine the output y[n] for the following signals a) x[n] = 8[n + 3] - 8[n - 3] b) x[n] = u[n] c) x[n] = u[n + 3] - u[n - 3] d) x[n] = u[n − 3] + u[n +3] -

I need help with this Digital Signal Processing question please. Answer in great detail.

Given the electronic circuit below: R3 R1 Vout Vin R4 L R2 a) Derive the transfer function between the output voltage and the input voltage (in terms of parameters R1,R2,R3,R4, C and L ) b) Let C=50 mF, L =1 H, R1=400 N, R2 = 42, R3 = 1KN, R4=100 K2. Compute the response of the circuit Vout (t) to the unit-step input signal Vin (t) = us(t) (assuming as usual that the initial conditions are zero) (Hints: m: 10-3, K: 103 , 1/0.05 = 20) c) Assuming Vin(t) : voltage i.e. Vout(0+) (assuming as usual that the initial conditions are zero) ? us (t) unit-step input voltage, what is the initial value of the output

A) Although the magnetic field for each phase of a 3-phase induction motor is merely switching back and forth between north and south poles, the resultant magnetic influence from all phases sets up a rotating magnetic field to cut the rotor conductors. a) true b) false B) In a two-pole stator winding of a 3-phase motor, how many revolutions does the rotating tr) magnetic field make in one cycle of the electrical current? a) one b) 60   c) 3600 d) none of the above
