A designer wants to represent all decimal numbers from 0 to 33. How many bits are needed? What are the binary representations for 0, 7, IS, 31 and 33? What is the largest value that can be represented?
Suppose we use a 4-bit unsigned binary representation to encode the rotational position of the shaft in Figure 3.14 instead of a Gray code. Identify all cases where more than one bit changes between adjacent code words.
a closed conical tank with diameter of 1.50 and height of 3.00 m, sitting on its circular base has 1.00m depth of water. Suppose the tank is upside down and is made to stand vertically that way using some device.
Sketch the waveform defined and explain how you would obtain its Fourier series - Develop the analysis as far as you are able.
The voltage across a 1-µF capacitor is given by v(t)=100 e-100t . Find expressions for the current, power, and stored energy. Sketch the waveforms to scale versus time.
A silicon diode with an area of 100mm´100mm is doped with ND=2e17cm-3 and NA=1e20cm-3. It has an IS=1fA, nonidealityfactor n=1 and tT=1ns. Consider room temperature of 300 Degree Kelvin.
consider the power system below.1. write the ybus matrix.2. identify the bus types and the unknown variables of the
How does the efficiency of a transformer at rated conditions and 60 Hz compare to the same physical device running a 50 Hz?
What determines the magnitude and polarity of the counter-emf in a dc motor and the counter-emf of a motor is always slightly less than the applied armature voltage.
Use electric circuit analysis techniques and Laplace methods to find the charge, q(t), on the capacitor as a function of time. The switch is closed at t=0 and the initial voltage V0 on the capacitor is 8 Volts.
By making a plot of output SNR versus demodulation phase-error variance for the case in which normalized mean-square error is 0.4%, show the region of satisfactory system performance. Repeat for a DSB system. Plot both curves on the same set of ax..
A circular loop TV antenna with 0.02 m2 area is in the presence of a uniform amplitude 550 MHz sinosoidal signal. When oriented for maximum response, the loop develops an emf with a peak value of 30 mV.
In addition, there are two 20 A, single-pole breakers protecting branch circuits supplying 277V lighting circuits. Is this panel classified as a power panelboard or an appliance and branch circuit panel-board.
