An x-y plane separates two materials. Material 1 covers z < 0, while material 2 covers the z > 0 region. There is no surface current or charge on the boundary between the two materials.Material 1 has a uniform electric field of E = x-hat + 2y-hat + 3z-hat V/m, and a uniform magnetic field of H = x-hat +2y-hat + 3z-hat A/m.
What are the electric and magentic fields in Materical 2, right at the boundary?
Explain the operation of sequential logic devices and evaluate the output waveform in relation to the clock for QA, QB and QC in the subsequent circuit and show the binary sequence represented by these waveforms
Consider a multimode silica fiber that has a core refractive index of n1 = 1.48 and cladding index n2 = 1.46. Find the critical angle, numerical aperture and the acceptance angle.
Frequency multiplers are used at the transmitter to bring up the frequency level to the transmitter level frequency. Why don't we use the crystal oscillator to generate the transmitter level frequency
1. What is the effect of sampling at a higher rate on the error performance of a digital modulation scheme 2. Suppose 16QAM was the modulation scheme used for this lab; would the error performance
Each pole of a 100kW, 250v flet-compound generator has a shunt field of 2000 turns and a series field of 7 turns. If the total shunt field resistance is 100 ohms, calculate mmf when the machine operates at rated voltage.
CDMA is a multiple access technique to allow multiple users to share the same bandwidth, based on the orthogonality of their spreading codes. CDMA is a descendent of the direct sequence spread spectrum (DSSS) technology designed for antijam (AJ).
Design a circuit that might be used as a trigger for a night-light. You are given a photoresistor whose resistance changes from 5k when inside a lighted room to 30k in a dark room. Design a voltage divider circuit that will provide a 3V
A 190-F capacitance is initially charged to 1190V . At t = 0, it is connected to a 1-k resistance. a) At what time t2 has 50 percent of the initial energy stored in the capacitance been dissipated in the resistance
Drift velocity the actual (physical) velocity of electrons along the wire. Transmission velocity the rate at which information can be transmitted electronically using conducing wires. How is it possible that the transmission velocity is so much faste..
a) If the excitation voltage E0 is equal to the terminla voltage ( 4kV ), what is the maximum real power which the motor can deliver without losing synchronism b) What is the rotor pole shift in electrical degrees, corresponding to the nominal loa..
