Describe the two common methods of correcting errors that occur on data links ? A frame check sequence (FCS) contains either a 16-bit or 32-bit sequence of bits. What is it and how is it derived? When FEC (forward error correction) is implemented, what types of errors can be corrected? How can one use FEC to correct burst errors?
A three-pole feedback amplifier has a loop gain function. - Determine the value of β that produces a phase margin of 80 degrees.
An external noninductive resistance of 1Ω isplaced in series with each phase of the rotor, and the motor isabserved to develop its rated torque at a speed of 1116 r/min.Calculate the resistance per phase of the original.
A 1 lb weight is suspended from a 0.005 in diameter wire. The unstrained resistance of the wire, R0, is 270 ohm, and its unstrained length is L0=36 in. The wire's gauge factor is 3.2. a. Calculate the psi tensile stress on the loaded wire.
A student project requires a 6 V DC power supply that can source 300 mA. The batteries for the power supply must last for a minimum of 8 hours of continuous operation. NiMH rechargeable batteries in AA size are to be used.
If wind power at this site varies as the ratio of heights raised to the 1/7 power, compute the ratio of power in the wind that appears at the tip of the top blade relative to the power that appears at the elevation at the tip of the bottom blades.
One of the operations involves soldering wire to a microchip. If all possible assembly orderings are equally likely, what is the probability that the soldering comes first or second?
A two-wire copper transmission line is embedded in a dielectric material with εr = 2.6 and σ = 2X10-6 S/m. Its wires are sperated by 3 cm and their radii are 1mm each. Calculate the line parameters R', L', G', and C' at 2GHz.
Draw the signal flow graphs for both the direct form I and direct form II implementations of this system as a 2nd-order system using only real coefficients.
Snicker's had determined that their target consumers are 15 to 29 year old men. 40% of all SuperBowl Viewers were 15 to 29 year old men. What was the TARGET CPM (TCPM) for Snickers ads during the 2016 SuperBowl?
If a RAM memory has a 5-to-32 row address decoder and a 6-to-64 column address decoder, and eight pins I/O, what is the size of the memory
show that for a square matrics the linear dependence of the row vectors imples the column vectors.conversely for a non square matrics either row vectors or column vectors are linear dependent.
Design a handheld hair dryer with the following specifications and realistic constraints: 1. It uses a 60 Hz, single-phase, 120 V r.m.s sinusoidal voltage source. 2. It has three settings low, medium, high.
