Repeat the preceding problem assuming a (23,12) Golay code.
PROBLEM 23:
A source has five outputs denoted [m1, m2, m3, m4, m5] with respective probabilities [0.41, 0.19, 0.16, 0.15, 0.9]. Determine the code words to represent the source outputs using both the Shannon-Fano and the Huffman techniques.
PROBLEM 12:
Determine the capacity of the channel described by the channel matrix shown below. Sketch your result as a function of p and give an intuitive argument that supports your sketch. (Note: q = 1 - p:). Generalize to N parallel binary symmetric channels.
The average power is not necessarily equal to the average current times the average voltage. To show this, find a voltage waveform and current waveform where each has a zero average value but their product has a non-zero value.
Obtain the optimum tap weights for a three-tap MMSE equalizer and at a SNR of 10 dB and b = 0:5.
A power amplifier has a gain of 20 dB and an input level of 2 volts. Assuming that the input and output impedances are the same, what is the voltage level at the amplifier output
a. The input G=0, H=0 is not allowed for this flip-flop. Why b. What is the excitation table for the GH flip-flop c. Use GH flip-flops to construct a counter to count the following sequence: 000 -> 001 -> 010 -> 100 -> 000
How would you know a system is linear by just looking at its input/output characteristic graph And what does the sensitivity of a sensor tells us about the sensor
sum up all the double words stored in memory area 60000h to 60100h. same problem as program 5 on pg 166. use good
Obtain the noise temperature of an amplifier with these two noise sources used as inputs if the difference in attenuator settings to get the same power meter reading at the amplifier's output is 1 dB, 1.5 dB, or 2 dB.
The student turnsaround and travels half the distance between his current location and his home beforechanging his mind again. This process of changing direction and traveling half the remainingdistance continues until the student reaches a certai..
Use Routh- Hurwitz method to determine if the system is stable or unstable. If it is unstable how many poles are in the right half of the s-plane (s^2+2s-5)/(s^3+2s^2-8s+6)
Compute the maximum and minimum spectral frequencies received by a mobile traveling at a speed of 100 Km/hr. What is the frequency of the received signal if the mobile is moving in a direction perpendicular to the direction of arrival of the trans..
If engines are randomly selected one at a time and tested, find the probability that the first non-defective engine is found on the second trial.
Eigenfunctions and LTI systems, The eigenfunction property is only valid for LTI systems. Consider the cases of nonlinear and of time varying systems.
