(A) Consider a communication system where the number of successful transsions out of 10 trials follows a binomial distribution. The success probability for each triat is 0,95, Let X be the random variable representing the number of successful transmissions. -Sketch the cumulative distribution function (CDF) of the distribution. 2- Find Skewness coefficients and check if the distribution is symmetrical or skewed to the right or left. 3- Find kurtosis coefficients, Check if the distribution is mesokurtic, leptokurtic or platykurtic. 4- Find the probability of getting at most eigh. successful transmissions. 5- Find the probability P(20 with a mean 2-1 calculate the probability that the noise is greater than 3 units.

Determine the region where the poles of a second-order system without zeros must be so that the settling time is between 1 to 4 seconds, and the overshoot percentage is between 16.30% and 4.6%. Draw the region

Suppose a power system consists of two isolated regions: a western region and an eastern region. Five units have been committed to supply 3090 MW as shown below. The two systems are separated by a transmission line that can handle a maximum transfer of 550 MW in either direction. If losses are ignored, calculate the spinning reserve for the overall system and for each region. Comment on the adequacy of the spinning reserve of the overall system, and for each region. (consider the effect on the power supply in each of the regions if the various generators fail). Repeat the above calculations and analysis if an average of 8% of the output of the generators is lost in the transmission and distribution system before reaching the load.

Question 7

Assume there are two digital chips on a PCB and 5V DC signals are being sent from one chip to the other. The distance between the two chips is 5cm, and the velocity of propagation is 10^8 m/s. The impedance looking into the sending chip is 25 ohms and the impedance looking into the receiver chip is 200 ohms. The microstrip transmission line between the two chips has a characteristic impedance of 50 ohms. (a) Draw the circuit diagram for this chip-to-chip communication scenario. (b) Draw the bounce diagram including the reflection coefficients, forward/reverse propagating voltages for 5 periods, and label the diagram. (c) Draw the voltage vs. time graph at the mid-point of the transmission line for 5 periods.

8.) Sketch the root locus, for positive K, of the system shown below using the (1, 1) Pade approximation for the delay. Note that this produces a 0° root locus for positive K.
