Determine the frequency response of the following causal IIR LTIsystem, where |a| < 1
y[n] = x[n] + a * y[n-L]
Determine the maximum and minimum values of the magnitude response.How many peaks occur in the magnitude response in the frequencyrange from zero to 2π? What are the locations of the peak and dips?
Convert to the z - domain and find transfer function H(z) =Y(z)/X(z)y(z) = x(z) + a * y(z) * z-L so H(z) = 1 /(1 - a * z-L)
The frequency response H(ejw) = 1 / ( 1 - a *e-jwL)
A voltage follower of the op-amp parameters are Ao = 5x 10^5, Ro = 75ohm, and Ri = 2 Mohm. The input voltage is Vs = 5V and Rs = 10 kohm. Find the output voltage Vo,the input resistance Rin = Vs/is and the output resistance Rout.
A uniformly doped abrupt pn junction (step junction) diode is fabricated. At room temperature 25% of the total space charge region (depletion region) is in the p-region. The built in potential is also measured to be 0.710V.
Describe and explain drift current and diffusion current in a PN junction in thermal equilibrium. What causes each. In which directions are the electrons, holes, electron current, and hole current flowing for each effect
A Si wafer is doped with Na = 5x10^16 /cm^3 of acceptors. In equilibrium at T=330K calculate, list the following for the Si wafer: Eg (Energy gap), ni (intrinsic concentration), n,p - the free electron and hole concentrations
Shirlee is working with a measurement tool that reports measurements in centimeters. Since Shirlee is unfamiliar with centimeters, she would like her centimeter measurements to be converted into yards, feet, and inches.
Write a simple shell script called mathmagic that takes two arguments in at call time and returns to the stdout the value of the two items entered, the value of the two items added together, the value of the two items subtracted
Develop the Boolean expression in POS form found by removing the static-zero hazards from the following expression. Your circuit must be minimized to receive full credit. Draw the schematic for the hazard-free circuit.
Write a sequence of instructions to initialize and run the timer to geneate an 800 baud rate clock. what would be the baud rate if the intial value of the timer was set to 9AH
b) Calculate the armature current at start c) The motor is now used as a generator. Calculate the speed of the machine if the armature current is 80A and there is a 230V at the motor's terminals. Assume a constant flux.
A control system is needed to control a small shopping center parking lot lighting system and the exterior lighting for the building. The design specifications require that the parking lot lighting and the exterior lighting turn on at dusk automat..
Select the appropriate resistor to add to the circuit in order to reduce the voltage across the bulb to the appropriate level. Choose the nearest 10-% resistor value and determine what its power rating should be.
A perfect conductor 2m long is moved at a speed of 36 Km/hr through a magnetic field having a flux density of 1.0 T. If a 1 resistor is connected across the ends of the conductor, calculate: (a) The induced voltage (b) The current in the circuit
