1) Determine the transfer of second-order highpass filter with a cutoff frequency of 900 Hz and passband gain of 1 using a butterworth type.
2) Design a filter for your transfer function from question.1 using the sallen-Key topology. Find all the values of the circuit elemnts and draw the circuit.
3) Given an analog signal
x(t) = 5 cos(6500pi t)+2 cos(8000pi t) +3 cos (12000pi t), for t>=0
sampled at a rate of 9000 Hz
a) Plot the spectrums for the range from 0 Hz to 25000 Hz. Make sure to label the frequncies.
b) sketch the recoverd analog signal spectrum if an ideal lowpass filter with a cutoff frequncey of 4.5 kHzis used to filter the sampled signal.
c) Determine which frequency (ies) will be the aliased one(s). Explain
Construction of different types of power transformer, significant energy savings
A proportional control system is to be used to control the wing flap of a jet airplane. The wind load is expected to cause as much as 600 in-lb of torque. The system should be able to keep the flaps with 5o of the set point.
give three methods that are used to express logic relationship between inputs and outputs of a logic gate, for example a three-inputs NOR gate.
What does "transfer function" of a filter represent What do the Amplitude Ratio (Gain) and Phase Angle represent What are the key differences between a real filter (the RC circuit) and an Ideal Filter (please read LPF Treated as an Ideal Filter)
The voltage across a certain load is V =1200*sqrt(2)*30 V, and the load impedance given by Z = 40 j30 ohms . Is the load inductive or capacitive Determine the power factor, complex power, real power, reactive power, and apparent power delivered to..
A 10 kW, 220 V, dc shunt motor has field and armature reistance of 110 ohms and .20 ohms, respectively. At no-load the motor runs at 1200 rpm and has an armature current of 5 A.
Seawater with a specific weight of 64.0 lbs/ft^3 is at a level of 4 feet above the centerline of the exit pipe. The tank is closed at the top and there is a pressure of 1 psig above the seawater. What is the velocity at the end of the pipe
What is the main cause of bit errors on this digital link? At the receiver, what is the rule that is used to decide whether to output a 1 or a 0?
a) Generate the State Transition Table, which should include the binary( ones and zeroes) values of the Flip Flop inputs which then enable you to determine next states based on current states. b) Draw the State Diagram for the system.
A circuit has a meter shunted by a parallel resistance (rs). With a current of 200 A. The meter can read a max of 1mA and has a residtance of 0.1 ohm. The shunt resistance is 0.0000005000025.
A U manometer reads 20 cm air as operating fluid and a given manometric fluid. A single branch closed tube reads 35 cm connected to point 1. If P2 = 1.2 ATM calculate the pressure in point 1 and the density of the manometric fluid.
A 3-phase, 60 Hz supply and two 3-phase synchronous machines are available. Determine the speed, and a suitable number of poles, for each synchronous machine to provide: a) A 3-phase, 180 Hz supply. b) A 3-phase, 500 Hz supply.
