Nonlinear Antoregressive with Exogenous Inputs (NARX) ModelConsidering the NARX network of Fig. P15.8, do the following:
a. Construct the state-space model equivalent of this single-input single-output recurrent network.
b. Repeat part (a) of the problem for the case when the network of Fig. P15.8 is expanded to embody two inputs and single output.
Once the sequence starts it will complete.If E=1 during the last output in the sequence the sequence repeats. Otherwise if E=0 the output remains constant at 1. The first thing they want in this problem is a Moore state diagram for the circuit.
A delta connected load consists of three identical impedances Z=45 at 60 degrees per phase. It is connected to a three phase, 208-V source by a three phase feeder with conductor impedance Zfeeder=(1.2+j1.6) Ohms per phase.
Sketch a time diagram similar to Figure 3.22 illustrating what happens when a frame gets lost between the sender and the receiver. It should be clear from your diagram how the protocol handles this situation.
Two voltage waves of equal amplitude, V0, and frequency w, propagate in the forward z direction in a lossless transmission line of characteristic impedence Z0. One waves is phase-shifted from the other by \o radians.
What causes the current gain to decrease both in the case of a low collector current and at a high collector current?
A 50 V DC power supply is connected to a 100 Ohm load resistor. The tested current flowing through the resistor is 0.49 A. find the internal resistance of the DC power suppy.
The current in a circuit is 100mA. Determine what the current will be when the resistance is increased by 100%.
Then find the phase relation between the total voltage and current; is it leading or lagging when the frequency is below resonance and above resonance; what is the nature of the circuit in those two regions(capacitive or inductive).
calculate the total power received at rx if the power being transmitted is 20w the distance for transmission is 5km

A balanced transmission line picks up an undesired signal with a 5-mW level. After conversion to an unbalanced signal using a center-tapped transformer, the undesired signal is 0.011 uW. Calculate the common mode rejection ratio (CMRR).
A plane wave is propagating along the z direction in a medium witha propagation coefficient (gamma) equal to (0.004+j2.5) a) What is the phase shift (in degrees) in the electric fieldfor two points along the z axis separated by 10 m.
