A baseband signal has frequencies from near dc to 4 kHz. To ensure ease of recovery, the signal is to be sampled at a rate 25 percent greater than the theoretical minimum. Determine the time interval (in ms) between successive samples.
Assessment on Electricity and Circuit Theory, What part of a cable are insulators and conductors? Describe, in terms of charged particles, why some objects are electrically attracted to each other, while others repel each other?
in the bottom of the 9th inning, the bases are loaded and the braves are down by three runs. chipper johns steps to the plate. twice he swings and misses. The crowd heads for the exits. the next pitch is a fast ball down the middle.
A new 24-bit processor is being designed for operation in a cell phone (you can assume the word-size is 24 bits). Suppose the following memory values are being stored in memory that is organized where each location is 8-bits wide (byte addressable..
The average orbital radius of Neptune is 2.8 billion miles. Given that distance, how long on average does it take light from the sun to reach the planet Neptune in hours (Speed of light in English system = 186,282.4 miles/second)
The input to a certain filter is given by Vin(t)=2cos(10000pi*t-15deg) and the steady state output is given by Vout(t)=5cos(10000pi*t+25deg). Determine the (complex) value of the transfer function of the filter for f=5000 Hz.
Suppose that the machining operation requires 1 kW, that the tool machine ihas 90 percent efficiency, and that the supply current is 14 A rms with a power factor of 0.8. Find the AC machine efficiency.
An extension cord is used with an electric weed trimmer that has a resistance of 13.7 O. The extension cord is made of copper (resistivity 1.72 x 10-8 ohm m) wire that has a cross-sectional area of 1.20 x 10-6 m2.
The time has come for XelPharm to expand. The board of directors has purchased another warehouse for a second distribution facility. It's located in an industrial area, about eight miles from the company's headquarters.
A P=900W electric motor with pf=0.82 lagging is connected to a 240 Vrms 60 hertz source. a) Draw an equivalent circuit showing impedance and phasor values for Vs, R and X. b) Find an Xc value to put in parallel with the motor which corrects the pf to..
