Assuming that a 5-bit ADC channel accepts analog input ranging from 0 to 4 volts, determine the following:
a. Number of quantization levels;
b. Step size of the quantizer or resolution;
c. Quantization level when the analog voltage is 1.2 volts;
d. Binary code produced by the ADC;
e. Quantization error.
For a short transmission line having a series impedance Z=R+jXL, write the relationships between the sending-end and the receiving-end voltages and currents. Assuming a line with R=0, XL=20 ohm feeding a 1MW load at 0.95 power factor
during winter you use an electric heater rated 1000W . heat transfer occurs through four walls each width of 5m and hight 3m layers of walls are concrete , paint, gypsum. temperature outside is 5 degrees celsius what is the temperature inside the ..
Are the systems stable For functions above, determine the steady state response for a step input. Determine the natural frequency , and the damping ratio and sketch the step response.
A linear digital filter Hd(z) is given below, and the sampling rate is T=0.1 seconds. Hd(z)=(z-j)(z+j)/(z-0.5)(z+0.5) 1. Show poles and zeros of Hd(z)in the complex z plane. Is this filterstable
A series-connected dc motor is designed to operate with a variable load. The resistances RA and RF are negligible. To attain high efficiency, the motor has been designed to have very small rotational losses. For a load torque of 100 Nm, the machi..
A 230V, 25hp, shunt DC motor draws an armature current of 90Aat full rated load. The armature resistance is 0.2 ohms and theshunt field resistance is 216 ohms. Determine the rotational lossesand motor efficiency at full load.
Developing secret codes has interested people for centuries. A simple coding scheme can be developed by replacing each character in a text file by another character that is a fixed number of positions away in the collating sequence.
Which type of A.C motor is used in the fan (ceiling fan, exhaust fan,padestal fan, bracket fan etc) which are find in the houses
A circuit has an 9 ohm resistor in series with a 0.30 mF capacitor. The input voltage is vIN(t) = 14 cos (400t - 30o) V. The output voltage is measured across the resistor. what is the magnitude of the output voltage
A certain cyclotron that has a magnetic field whose magnitude is 1.8 T is designed to accelerate protons to a kinetic energy of 25 Mev. (a) What is the cyclotron frequency for this cyclotron (b) What must the minimum radius of the magnet be to ach..
Describe the fundamental safety and health principles behind the control of hazardous energy standard. Be sure to touch on what hazards the standard is designed to circumvent. In your discussion, include three examples of situations where locko..
Two charged concentric spherical shells have radii 10.0cm and 15.0cm. The charge on the inner shell is 4.00X10^-8C, and that on the outer shell is 2.00X10^-8C. Find the electric field (a) at r = 12.0cm and (b) at r = 20.0cm.
