Asuuming that an 8-bit ADDC channel accepts analog input ranges from 0 to 12 volts, determine the following:
a) number of quantization levels
b) step size of the quantizer
c) Quantization level when the analog voltage is 9.25 volts
d) binary code produced by ADC
e) Quantization error
a- The adjustability of the potentiometer can be used to obtain an adjustable output voltage b- Both power supplies must be used so that the adjustable voltage can have both positive and negative values
The photoelectric threshold wavelength for Tungsten is 2300 Å. Find the energy in eV of the emitted electrons from the surface by ultraviolet light of wavelength 1800 Å.
A 78oham lossless planar line was designed but did not meet a requirement. What fraction of the widths of the strip should be added or removed to get the characteristic impedance of 75oham
We are required to create a digital clock for the upcoming project. The class has been very disorgainzed and hard to follow, thus I've had a hard time keeping up with what's actually going on and don't quite understand all the material.
The voltage output from a two active gage of Wheatstone bridge was 3.5 mV. The excitation voltage was 5 V. Nominal resistance of the strain gage was 350 ohms and the gage factor was 2.05. Calculate the force in pounds on the steel rod.
Assume you buy a 1 kOhm resistor with +/- 20% tolerance in its value. You would like this resistor to consume at most 2 W of power, otherwise it might burn. What is the highest power supply in V you would use to power it
The DC resistance of the primary windings of a certain transformer is found to be 22ohm while the resistance of the secondary windings is 0.8ohm. When a 60 Hz sinusoidal source is connected to the primary "with the secondary open circuited"
A 2.4KV, single-phase circuit suppllies a load of 250KW at a lagging power factor, and the load current is 160A. If it is necessary to improve the power factor, determine the following: (a)The uncorrected poer factor and reactive load.
A 230 V DC series motor has an armature circuit resistance of 0.2 and a eld circuit resistance of 0.1. At rated voltage, the motor draws a line current of 40A and runs at a speed of 1000 rpm.
a boost converter operates at 20 khz, and converts power from a solar panel to a battery bus. the panel has norminal volate of 16v and current up to 3 A. the battery bus is 48 v. the transistor can be modelled as a 0.5 v constant forward drop.
Using 8-bit bytes, show how to represent 123, clearly state the byte values using hex and the number of bytes required for each context. Simply indicate the case if the code is not able to represent the information.
Calculate the total complex power, total current drawn and the total power factor and Y-connected load with an impedance of (1+ j 6) ohm per phase,
