Some manufacturers are planning to offer dash-mounted web access in vehicles. Do you think this is a good idea? Why, or why not? What are the ethical implications of this for the engineers working for an automobile manufacturer?
When writing or speaking about reactance, how do we distinguish inductive reactance from capacitive reactance. How are resistances, inductive, and capacitive reactance treated in calculations of AC voltage and current.
Production cost refers to prime cost plus 1. factory, administration and sales overheads 2. factory overheads 3. factory and administration overheads 4. factory, administration, sales overheads and profit
r = 4.2, d = 0.079 cm, and tan δ = 0.02, and with copper conductors 0.5 mil thick. Use CAD to plot the insertion loss versus frequency in the pass band of the filter, and compare with the lossless case.
Finding values of a composite discrete time signal, A discrete time signal x(n) = x(n-1) + x(n-3) with initial conditions x(0) = 0, x(1) = 1 and x(2) = 2 is examined and the first 51
Suppose we want to construct an amplifier with a closed-loop gain of 50. We want the gain to vary by no more than +/- 5% while the open-loop gain varies by +/- 50%. Determine the values for a and b that will satisfy these constraints.
Determine the voltage v(t) (the voltage across the inductor) in circuit 2 (note that v(t) is voltage in the time domain. Assume f=60Hz)3. Determine the reactance needed to be added to a load connected to a load connected to a 480 VACrms source in ..
A tennis ball, having a mass of 50 g, travels with a velocity of 200 km/h. What is the equivalent wavelength of this "particle"? Compare your result with that obtained in Problem I above and discuss the difference.
At what frequency does an RC low pass filter attenuate by 6dB(output voltage equal to half the input voltage) What is the phase shift at that frequency
Describe the operation of the series RC circuit. The discussion must address phase angle relationships of current and voltage. The answer must include the effect of source frequency on the voltage drops across the resistor and the capacitor at ver..
Any causal signal x(t) having a Laplace transform with poles in the open-left s-plane (i.e., not including the j axis) has, as we saw before, a region of convergence that includes the j axis, and as such its Fourier transform can be found from its..
Assume that an oven has an electronic thermometer attached to circuitry with two outputs: one (H) is asserted when the temperature is above h, and the other (L) is asserted when the temperature is below l. Design a circuit that will turn the oven
A 50 (ohm) lossless transmission line is terminated in a load with impedance Z= (30-j50) ohm. the wavelength is 8cm. Determine: (a) reflection coefficient (solved: 0.1 - j0.56 or 0.56 angle -79.9)
