An eight-character source has probabilities:S : 0.35, T : 0.25, U : 0.20,V : 0.07, W : 0.05, X : 0.04, Y : 0.03, Z : 0.01. let a character stream fromthis source be Huffmancoded. Then, let groups of consecutive four message bitsbe encapsulated into 8-bit SEC-DED Hamming code words.Suppose the following two Hamming are received:0101111001100001.(a) Correct any potential transmission errors.(b) What are the original eight transmitted message bits?(c) Partially decode these messagebits into the original characterstream from the source.
A balanceed three-phase load of 15 MA with a lagging load factor of 0.85 is supplied by a 115KV subtransmission line. if the line impedance is 50+j100Ohm per phase, determine the following: (a) The line current of the load
Find the appropriate subchannel modulation format (note: the number of constellation points in the modulation mapping scheme should be the power of two).
If you have a purely inductive load with a reactance of 2/377 O connected to the 120Vrms 60 Hz (i.e., f = 377 rad/sec) AC line, what value of capacitor (in Farads) must be put in parallel with it to set the power factor to one
Study code acquisition in frequncy hopping spread spectrum communication systems.Describe and explain why it is necessary.Design and demonstrate a code acqusition method.
A silicon diode has a doping profile such that ND = ax3. What is the depth of the junction assuming the p side is uniformly doped with NA per cubic cm. Assume the x origin is at an ideal ohmic contact on the n side of the diode.
Your design calls for a 4-way multiplexer. However, when you go to the stock room, all you can find is a 2x4 decoder, AND gates, OR gates, and inverters. Show how you can create the 4-way multiplexor with a single 2x4 decoder and the appropriate m..
Design a counter with TFFs that goes through the following binary sequence: 0, 2, 5, 3, 6, 4. And Design another counter thatgoes through 0, 5, 4, 6, 3, 4.
three coins are tossed. Describe the following events: A. at least two heads occur. B. At most one head occurs. C. Exactly two heads occur. D. No heads occur Find the probability for the occurence of each event.
Let the input to a singly-balanced mixer, f(t), be given by V0 Sin (2 pi fs t). The local oscillator input p(t) is a square wave, alternating between 0 and +1 volt. The freqency of the square wave is 10 MHz, while for the input, fs is 100 KHz.
Design a circuit to multiply a 2-bit unsigned magnitude binary number by 1, 2, 3, or 4 to produce a 4-bit output
What bit pattern (after you remove the beginning and ending flags and any stuffed bits) will the receiver pass on for higher level processing?
The courses offered are usually of two types: practical, such as woodworking, word processing, and car maintenance; and humanistic, such as history, music, and fine arts. To satisfy the demands of the community, at least 10 courses of each type mu..
