The electric field in the wave has the instantaneous expressionE(z,t) = iy 3 sin(3pi.109t + 100piz 600), V/m.i) What is the frequency of the wave in Hz?ii) What is the wavelength of the wave in m?iii) What is the direction of propagation of the wave?iv) What is the phase velocity of the wave?v) What is the relative refractive index of the wave?vi) What is the polarization of the wave?
The total sunlight at noon on a clear summer day is just over 1KW/m^2. Assuming a solar panel with 20% efficiency, and an output voltage of 20V, estimate the output current of a one square meter panel in full sunlight.
First draw the transmit con-stellation and the receive constellation with ideal phase tracking and sampling. Note:they are obviously the same constellations. Now, assume that receiver synchronization is off by a phase angle.
A single-phase, 60-Hz power will be transmitted through the transmission line Each subconductor's radius is 10 cm. There are two configurations, the first one is setting subconductors A and B as a bundle, and C and D as another bundle
Show the design of a 2-1 Mux: (a) using a NAND/NAND implementation, (b) using a NOR/NOR implementation. Which would you prefer to build and why Assume that you have all variables and their complements available.
An n-channel JFET needs a NEGATIVE voltage applied to its GATE, relative to its SOURCE. If you have a single POSITIVE supply applied to the MASTER loop of a JFET, the mid point of the voltage divider will also be a positive voltage
a) If the internal resistance of a voltmeter is 100x bigger than the output impedance of a circuit, what is the loading error b) If the internal resistance of an ammeter is 10x smaller than the output impedance of a circuit
A three-phase load is Y-connected. The load has a phase voltage of 139 V and a phase current of 49 A. Each phase of the load consumes 5.1 kW of power. (A) Sketch and label the load. Find (b) the line voltage, (c) the line current, and
