If a lowpass filter with a DC gain of 1 and 3 poles, all at 3KHzis used as an antialiasing filter, at what frequency will the aliased signal ( 5KHz) appear abd wgat will be the amplitude of the aliased signal.
Draw a block diagram for a datapath that contains: an 8-word, three-port register file; an ALU that accepts operands either from the datapath or from an external source; and a shifter that shifts the A operand from the register file before it goes..
A 208-V,60-Hz,three phase power system consists of an ideal 208-V,Y connected, three phase generator connected through a three-phase transmission line to a Y-connected load. The transmission line has an impedance of 0.06 + j0.12 ohms per phase
A three-phase, wye-connected, 20-MW load of power factor 0.866 lagging is to be supplied by a transmission line at 138 kV. It is desired that the line losses not exceed 5 percent of the load. If the per-phase resistance of the line is 0.7 Ohm
Assume there are five numbers stored in locations 20 to 24. Write a machine language program to add these numbers and store the result in location 25.
an amplifier with an input resistance 10kohm, when drieven by current source 1microA and a source resistance 100kohm has a short circuit output current of 10mA and an open circuit voltage of 10 V. The device is driving a 4kohm load.
A solenoid of 1000 turns energized by a current of 250 mA. A flux meter measures a total flux of 1.0 mWb through the solenoid. The core has an average path length of 25 cm and a cross-sectional area of 6.5 cm2.
Indicate the closest value to the change in decibels of the received signal for the given parameter change. The distance between transmitter and receiver for a one-way communication path is halved.
A six pole, 400 V d.c. motor draws 110 A from the supply. The shunt field resistance is 200 Ohm and the armature resistance is 0.5 Ohm. The armature is wave wound with 600 conductors operates at a speed of 1200 rev/min when supplying full load.
Measurements on sodium have provided the following data: resistivity 4.7 ×10-8ohm m, Hall coefficient -2.5 × 10-10m3C-1, critical wavelength of transparency 210 nm, and density 971 kg m-3. Calculate (i) the density of electrons, (ii) the mobility, ..
A voltage source 100(angle 0 degrees) is in series with a 200 ohm resistor and a cpacitive reactance of -100 ohms. a) What impedance,Zl, in parallel with the capcitor would absorb maximum AVERAGE power
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..
A linear-phase FIR filter should be designed with the ideal magnitude response shown in Figure 1 which represents an narrow band-pass filter. The lower cutoff frequency, fL , is 2,000 Hz, and higher cutoff frequency, fH , is 3,600 Hz.
