causal LTI discrete system whose transfer function is given by:
(H(z) = (z - 0.5) / ((z-e^{ln(0.16/z)})(z-0.2))\)
find the impulse response sequence, h[k], for all k.
Check initial and final values of the impulse response sequence using appropriate means.
Is the system stable? Why or why not?
Hint: Rewrite H(z) in a standard form and use Partial Fraction Expansion techniques.
With conditions remaining the same as in part (a), we would like to reduce the relative deadline for T3 to improve the quality of service. What is the shortest deadline that we can choose for task T3 such that all tasks will meet their deadlines
The bottom of the conduction band at one end of a silicon resistor is at the same energy level as the top of the valence band at the other end. What current flows through the resistor if the resistance is 1.12 kOhms
The R2= 6 homs load in the circuit is absorbing four times as much average power as the R1 = 20 ohmsohms load. The two loads are matched to the sinusoidal source that has an internal impedance of 500 (angle) 0 1)What is the numerical value of a1
Ten multimode glass fibers (n1 = 1.48, n2 = 1.45) are spliced together. Each fiber is 2 km long and has a loss rate 2-dB/km. Each splice adds 1 dB of loss. If the output power of the source is 7 dBm and radiates uniformly in a 60 degree half cone
What is the RF bandwidth occupied by signal? What is the frequency range of the transmitted RF signal?
A bowling ball is placed on a coil spring. The spring constant is 400N/m. When the bowling ball is placed on the spring, the spring compresses down 0.1m. If the spring is vertical how far will the bowling ball go
What is the uncertainty in position of an electron of an atom if there is ± 2.0 x 10^7 m·sec-1 uncertainty in its velocity Use the reduced Planck's constant and electron mass = 9.109 x 10-31 kg.
The following measurement were made on a two-port resistive circuit. With port 1 open, V2 =15V, V1 = 10 V, and I2 = 30 A. With port 1 short-circuited, V2 = 10 V, I2 =4 A, and I1 = -5 A. Find the parameters of the z-parameter two-port.
