BCH codes are binary block codes that allow multiple errors per code word to be corrected. An (n, k, t) BCH code has rate k/n, and can correct t errors per block of n symbols.
By using the technique illustrated in Example, examine the relative performance of (63,30,6) and (255,123,19) BCH codes. Assume PSK modulation and compare both BCH codes to the performance of the un coded system.
Why Power is Zero (0), in Pure Inductive, Pure Capacitive or a circuit in which Current and Voltage are 90 Degree out of phase?
Traceability ladders:- length (adapted from Scarr)- mass (reprinted by permission of the Council of the Institution of Mechanical Engineers from Hayward).- show the above using diagrams.
If we connect the two diodes from Problem 6 in parallel, andforce (using a constant current source) 500μA through them, what will the voltage be across each diode, and what will thecurrent be in each diode
determine whether a three-bit number, a3, a2, a1, is equal to another number, b3, b2, b1, or if it is greater than that number. (We do not need an output for less than.) a. Show how the 7485 would be connected to accomplish
A 20-hp, 250 V shunt-DC motor has an armature circuit of 0.22 ohms and a field resistance of 170 ohms . At a low-load, the speed is 1200 rpm and the armature current is 3 A. At full-load, the current is 55 A, and the flux is reduced by 6%
Draw a truth table for Sum 0 and COUT0. What is it called if you add two negative numbers and get a positive result
Explain why a PID controller is not a good idea for this process. Use Matlab to design a PD controller for this process. Repeat the design, but this time use a lead-lag compensation network to cancel the 0.731 time constant and replace it with a 0..
Design a stripline transmission line for a 70 Ohm characteristics impedance. The ground plane separation is 0.316 cm and the dielectric constant of the filling material is 2.20. What is the guide wavelength (lg) of this TL if the frequency is 3.0 GHz..
A designer wants to represent all decimal numbers from 0 to 33. How many bits are needed? What are the binary representations for 0, 7, IS, 31 and 33? What is the largest value that can be represented?
What are IDS and IPS? What can they protect them against? Write a 2-3 page paper that fully answers the questions.
In part (b) which should be the set point of G2 for the system frequency to be 50 Hz? What would be the load sharing now?
Assuming isothermal surface conditions, determine the allowable electrical power dissipation per board for the cooling arrangements:
