Interface conditions in layered structures. Two flat dielectrics of thickness d and dielectric constant ε1 and ε2 are placed on the two sides of a conducting sheet of thickness t. The electric field in free space to the left of the materials is given and is normal to the surface of the dielectric, as shown in Figure 4.72.
(a) Calculate the electric field intensity everywhere in space.
(b) What is the potential difference between the left and right surfaces (the potential difference on the three layers).
Assuming that a 12-bit ADC channel accept analog input ranges from 0 to 20 volts, determine the following a) number of quantization levels b) step size of the quantizer or resolution
Four hundred grams of nitrogen gas (molecular weight=28g/mole) are stored in a 10-liter container. Set up an excel worksheet to determine the pressure of the gas (in atmospheres) as a function of temperature and volume, assuming nitrogen is an idea..
A delay function should be created such that each time a new value is to be displayed on the oscilloscope it is followed by the determined time delay such that all data is output via the port at a rate of 2Khz. Change the time delay such that the ..
Consider the circuit as shown below. If Vin peak voltage = 12V, Calculate the output voltage Vo. Open loop voltage gain of the Operational Amplifier A=10,000. The voltage drop across the diode is 0.7 V.
If a seventh-order system has a row of zeros at s^3 and two sign changes below the s^4 row, how many jw poles does the system have
An amplifier has an input resistance of 1 k Ω, an output resistance of 200Ω, and a short-circuit trans-conductance gain of 0.5 S. Determine the open-circuit voltage gain, the short-circuit current gain, and the open-circuit trans-resistance gain.
Copper has one conduction electron per atom, that is, each atom contributes one electron that is free to move through the solid.
Describe what happens in terms of set point, feedback signal, error signal, and arm position.
A railway train is fitted with three engine/transmission units that can be assumed to exhibit a constant hazard with a mean life of 200 h. In a 15 h working day, calculate the probability of a train having: (a) no failed engine/transmission units
A student project is required to be portable and hand held. It requires 6 V DC power at a current of 150 mA. The batteries for the power supply must last for a minimum of 7 hours of continuous operation.
Discuss the effects that varying the values of K and B has on the steady-state error in unit-ramp response. Sketch typical unit-ramp response curves for a small value, medium value, and large value of K, assuming that B is constant.
Determine whether the following discrete-time systems are causal or noncausal, have memory or are memoryless, are linear or nonlinear, are time invariant or time varying. In the following parts, x[n] is an arbitrary input and y[n] is the response
