A charge density is uniformly distibuted over a linear section from 0<x<1 such that the charge density is 4ε. find the potential and the electrical field across the region assuming that V(1)=8 V(1)=0.
1.) (a) What is the difference between the sign-magnitude and 2's-complement systems of representing signed binary numbers. (b) What is the advantage of using the 2's-complement system to represent signed numbers.
The steady-state response is due to simple poles in the j axis of the s-plane coming from the input. Suppose the transfer function of the system is: H(s)=Y(s)/X(s)= 1 / (s+1)^2 + 4 a. Find the poles and zeros of H(s) and plot them in the s-plane.
A wire is bent in the form of a half loop of radius a = 10 mm and charged with a line charge density XL = 10-9 C/m. Calculate the field intensity at center of the loop.
A lossless transmission line, with characteristic impedance of 50Ω and eletrical length of l=0.27λ, is terminated by load impedance 40-j25Ω. Determine voltage reflection coefficient.
design a sequential circuit that continuously computes the function 2X + 3 or 3X + 1 where the variable X is a three-bit unsigned integer available on a serial interface. A special external data signal (DATA_READY) is asserted
A 480 V permanent magnet ac motor is consuming 10 kW at power factor 0.80 lagging. Its speed is 1800 rpm. The winding resistance is 0.5 ohms per phase. Core losses are 100 W.
A bandpass filter with a center frequency of 6kHz, a 3dB banwidth of 1 kHz, and a 50 dB bandwidth of 2kHz is connected to a signal generator that outputs a one volt square wave at a frequency of 2kHz. A spectrum analyzer is connected to the filter..
Let O be a measurement operator for the of dots facing upwards on a 6-sided 'quantum' die-- a die that can be put into superpositions of states and then measured. The set of possible outcomes is {1,2,...6}.
A mote draws an average of 200mA when "awake", 0.1mA when "sleeping", and 400mA (total) when "transmitting". Transmitting data takes 2ms, and sensor acquisition takes 1ms. If the maximum size battery available is 5000mAh
Look at the resistor illustrated. Based on your knowledge of the resistor color code, what are the resistance value and tolerance of this resistor?
Let y[n] = Odd{x[n+1]}, where Odd{f[n]} takes the odd part of f[n]. Determine if this system is a. Linear b. Time invariant c. Causal For each part, either show proof that the property holds or show an example that it does not.
The nameplate on a 50-MVA, 60-Hz single-phase transformer indicates that it has a voltage rating of 8.0-kV: 78-kV. An open-circuit test is conducted from the low-voltage side, and the corresponding instrument readings are 8.0kV, 62.1A, and 206kW.
