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.
A certain internally compensated (dominant pole) op amp has a dc gain of 200,000 and 3 dB bandwidth of 5 Hz. Sketch the Bode plot of the magnitude of the open loop gain to scale.
A three-phase, wye-connected, 220-V, 10-hp, 60-Hz, six-pole induction motor has the following parameters in ohms per phase referred to the stator: R1 = 0.294; R2 = 0.144; Xn = 0.503, X12 = 0.209;XM = 13.25.
design a full-wave bridge rectifier to deliver 12dc with less than 0.1v ripples into a load drawing 100ma. specify
Two in finitely long, very thin wires lie on the x and y axes and carry currents as shown in Figure. Show the direction of the forces on the wires due to the magnetic fields on the positive and negative part of each axis, assuming that Ix and Iy ar..
What are the essential features of an ideal op amp? Identify the terminals of an op amp. Draw its equivalent circuit. Define virtual ground and what is difference amplifier? Draw its circuit. Define C.M.R.R.
our senior design team is designing a force sensor to measure a force signal and analyze the signal with a microcomputer (binary system). The analog force signal is between 10 N and 70 N and has the frequency bandwidth of DC - 1000 Hz.
You are hired by a leading credit card company, Ford Chase Bank. One of their directos, Julie Hollas wants you to perform a small calculation for her. A customer wants to charge a Japanese robot to his credit card.
determine the minimum sampling rate necessary to sample and perfectly reconstruct the signal x(t) = sin(6280t) / (6280t).
Calculate the number of wind generators required to produce the equivalent energy of a 600MW CCGT operating at 80% load factor. Assume the average wind speed is 8 m/s, rotor diameter is 80 m, and conversion efficiency (coefficient of performance, Cp)..
A certain voltage is + 14.7 V for 24.8 ms and -14.7 V for the succeeding 24.8 ms and continues oscillating back and forth between these two values at 49.6 ms intervals. The voltage is present across a 64 resistor.
Calculate the stator reactive voltage drop IXs and hence with reference to a phasor diagram calculate the magnitude of the generated voltage E. - what is meant by the load angle of a synchronous motor.
The current in a device varies with time according to the function: i(t)= 3e^(-t/T) A. Where T is the time constant. How many time constants are required for the current to drop to 250 mA
