Equipment:6A DC power supply,pushbutton panel(1 normally closed(reset push button) and 3 normally open)and with indicator lights,relay,wires,1 PNP diffuse sensor(24V),1 motor(24V). Design a simple circuit diagram,to complete the following task.
1)Green lamp light up when the system is ON.
2)Once the pushbutton is pressed, Green Lamp turns OFF and Red Lamp turns ON,Motor starts to spin.
3) Once the sensor detect the motor rotate 1 revolution, Red lamp tuns OFF and Green Lamp turns ON to indicate the system is ready.
4)Anytime the Reset Pushbutton is presser the system will STOP.
Design the electrical system for a shopping center with 500,000 square feet at least 30 spaces of three different sizes (5,000, 10,000 and 25,000 sf). They may be offices, banks, restaurants and shops.
Determine the cost of the energy delivered by this battery per kilowatt hour. Compare to the $0.12 per kilowatt hour for energy purchased from electric utilities in the United States.
Design a MOS differential amplifier to operate from +/- 1V power supplies and dissipate no more than 2 mW in the equilibrium state. The differential voltage gain Ad is to be 5 V/V and the output common-mode dc voltage is to be 0.5 V.
Despite the advantages to the synchronous alternator there is a downside and this has to do with keeping the load balanced on such a machine. Why is balancing the load so important to the synchronous alternator?
Design a filter for a biomedical instrument to eliminate DC (f = 0), 500 Hz tone, and its corresponding harmonics. The system sampling rate is 2,000 Hz. Place all the required poles at the origin to obtain a FIR filter.
A) What is the magnetic field at a point along the axis of the coil, 0.89 m from the center B) At what distance from the center along the axis is the magnetic field magnitude 1/11 as great as it is at the center
Many hallway and some room lights are wired so that they may be controlled from either end of the hall or room. This is called a two-way or three-way switch (references vary). Explain why this is equivalent in operation to an XOR gate.
The balanced 60Hz waveform sample that we must modulate is the point where t=4.4ms. The DC voltage from rail to rail is 300V. assume the q axis and a axis are in same direction. The use of mathCAD is recommended.
Design a circuit that will add either 1 or 2 to a 4-bit binary number N. Let the inputs N3, N2, N1, N0 represent N. The input K is a control signal. The circuit should have outputs M3, M2, M1, M0, which represent the 4-bit binary number M.
A resistor R, capacitor C, and voltage source Vs= 100 cos 300t Vare all in series. If the average power dissipated by the resistor is 150 W and the rms capacitor voltage is $) V, determine R and C.
A signal has a fundamental frequency of 1000 Hz. What is its period? Assume the signal has a peak amplitude of 1 Volt and that the instantaneous power is equal to the square of the voltage, then compute the average power of the fundamental frequen..
What is the approximate discrete-time equation the models the continuous-time impulse response for fs=1kSa/s and RC=10^-2?How to solve this problem?
