Let x(t) be a signal with x(t)=0 for t<3. For each signal given below, determine the values of t for which it is guaranteed to be zero.
(a) x(1-t)
(b) x(1-t) + x(2-t)
(c) x(1-t)x(2-t)
(d) x(3t)
(e) x(t/3)
A given peripheral has 3 address lines (allowing access to 8 internal addresses) and requires that address lines A2-A0 to be used. It is desired that this peripheral occupy the hex address range, EB80-EB82 in a given computer system memory map
Tones Input In To An Amplifier, Suppose two tones are input in to an amplifier. The tones are pure sinusoids with one at frequencies 8GHz and the other at frequency 8.03GHz,(delta f =0.03GHz).
Create a flowchart and pseudo-code for generating a report that prints all of the movies, with all movies made by the same director on one page, as well as the number of movies by each director.
During the cyber security activity conducted in class by Renee Etoty, you were asked to identify systems that were conducting or experiencing cyber attacks. You will use the data provided during this activity to develop a program to display.
Semiconductor A has a bandgap of 2.5eV while semiconductor B has a bandgap of 1.5eV. What is the ratio of the intrinsic carrier concentrations in the two materials (niA/niB) at 300K
An AC Voltmeter uses a bridge rectifier and 100 ohm PMMC which requires a 1mA DC current for full-scale deflection. Assuming ideal diodes, calculate the value of the multiplier resistor to obtain full scale deflection with 10 V AC applied to the i..
(a) A Ge bar 0.1 cm long and 100 m2 in cross-sectional area is doped with 1×1017 cm-3 gallium. Find the current at 300 K with 10 V applied. (b) Upon a steady illumination uniform excess carriers are generated in the Ge bar.
Consider the following differential equation, where x(t) is the input and y(t) is the output: d/dt y(t)+5y(t)=2x(t) Suppose the input is x(t) = 4u(t) and the initial condition is y(0-) = 6 1. What is the impulse response for the system
1. a nichrome wire 12 ft long and .011 inch diameter conducts 1.83A when 120v are applied. what is the resistivity of nichrome 2. Copper windings of an electric motor at room temperature of 25 degrees C has resistance of .20(r).
If the work output is 10kW, find the required heat transfer rate from the high to the low temperature source, and the required heat transfer rate to the low temperature source. What is the themal efficiency of the engine
in step index fiber the core of diameter D has a refractive n1, which is typically equal to 1.48. core is typically surrounded by the cladding of slightly lower index. Where n2=n1(1-delta). The parameter is simply called the index difference.
three single-phase transformers rated at 250kVa, 7200V/600, 50Hz, are connected in wye-delta on a 12470V, 3 phase line, if the load is 450kVA, calculate the current in the incoming and outgoing transmission lines and in the primary and secondary w..
