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.
(a) Show the truth table of a 3-input-8-output binary decoder (without enable logic). (b) Construct a 3-input-8-output binary decoder using NOT, AND and OR gates (without enable logic).
An n+p junction with a long p-region has the following properties: Na=10^16 cm-3, Dp=13 cm2s-1, µn=1,000 cm2V-1s-1, tn=2×10-6 s. If we apply 0.7 V forward bias on the junction at 300 K, what is the electric field in the p-region FAR FROM the junct..
Explain why a PID controller is not a good idea for this process. Use Matlab to design a PD controller for this process. Repeat the design, but this time use a lead-lag compensation network to cancel the 0.731 time constant and replace it with a 0..
If the energy gap separating the valence and conduction bands in diamond is 5.4 eV, what is the maximum wavelength (in metres) of radiation that can be absorbed by this material
Suppose that OFDM is used with 15 kHz subchannels. (Two subchannels are used as guard channels on either side of the band.) Specify an OFDM symbol rate and modulation format for each subchannel that can achieve the target rate.
he sensor to be used has a transfer function of ? Q volts, where Q is in gal/min, and an output impedance of 2.0 k?. Tests show that the output of the sensor has 60 Hz noise of 0.8 V rms. Design a signal-conditioning system, including noise filter..
Design a suitable amplifier using a combination of these stages. Your design should utilize the minimum number of stages and should ensure that the signal level is not reduced below 10 mV at any point in the amplifier chain.
A shunt regulator utilizing a zener diode is biased on through a 100-ohm resistor. Determine the change in the regulated output voltage for the two situations below: a) VI changes +2.0 V, ILoad constant b) ILoad changes +100 mA, VI constant
An inverting amplifier With nominal gain of -20V/V employs an op amp having a dc gain of 10^4 and a unity-gain frequency of 10^6 Hz. What is the 3-dB frequency f3dB of the closed-loop amplifier
Desing a logic Circuit that receives an array X(4 bits:X1,X2,X3, and X4) and makes it available as an output O(4 bits: O1,O2,O3, and O4) after one clock delay, subject to the control of input signals : "a" and "b". If a=b=0, then the data is NOT t..
Suppose we want to construct a parallel plate capacitor of C= 1[F] using square plates. (a)If the dielectric is air (Xr= 1), and the plates are separated by 1 cm, what dimensions will the plates have
a plane wave is obliquely incident onto the planar interface between mismatched, lossless, nonmagnetic, uniform media, yet undergoes no reflection. If incidence is at 54 degrees to the normal, at what angle to the normal does the transmitted wave ..
