- Beginning with one start bit followed by 21 data bits, 2 parity bits and 1 stop bit:
- a) What are the total number of bits in the frame?
- b) What would the overhead and throughput be (answer in percent)?
Step by step
Solved in 2 steps
- a. Compute for the data efficiency of transmitting if the data format is a General Synchronous Data Frame. b. For an asynchronous data transmission (wherein 1 byte of data is accompanied by a specific number of auxiliary bits), how many start and stop bits are there if the data efficiency in transmitting is ? The number of start bits is equal to the number of stop bits.Assume that the 8-bit input word is 11101011: I. Please calculate the check bits (code). II. Suppose now that data bit 5 sustains an error and is changed from 0 to 1, recalculated the check bits. III. Now compare the new check bits with the old check bits to find the position for the data error bit.In single precision (IEEE-754 standard), 8 bits are used for storing the exponent (the bias is 127), and 23 bits are used for storing the mantissa. (a) What are the smallest and the largest positive numbers that can be stored in single precision? (b) What is the smallest value of the mantissa that can be stored?
- Write a small report about hamming code for error correction for a given frame. and give examples of different size frames , and show how single bit errors are corrected.4. Using a combination of ASK, FSK and PSK: b) Sketch the transmitted signal for the following bit stream: 10110011 01110100 11000001 c) What would be the data rate of this system if 20,000 signals were sent per second? d) What would be the effective bit time (not the signal time)? e) Could this be sent on a channel with a signal to noise ratio of 20 dB and bandwidth of 11,000 Hz?Are you able to differentiate between the least significant bit and the most significant bit in a given set of data?
- Manchester encoding guarantees frequent clock synchronization by changing signal values. What is the maximum number of bits which may be encoded without a signal change? (Note: The way this question has been asked. you are not to include the bit which includes a signal change in your count)Computer Science Construct a hamming code by adding a parity bit to a two data bit stream the parity should be even 1- show all the possible code words 2- What is the minimum Hammin distanceTwo-dimensional Parity checking... ...always detects 7-bit errors. ...never fails to detect single bit errors. ...never detects 6 bit errors. ...sometimes detects 6-bit errors.

What is the average number of bits required to encode a character?Assume that a system uses 10-bit floating-point representation based on the IEEE floating-point format, in which: . There is 1 sign bit. There are k= 6 exponent bits. The exponent bias is 31. . There are n= 3 fraction bits. ● Convert the decimal number -5.5 into the 10-bit IEEE floating point representation explained above. Write the final result in 10-bit binary format. Show your steps.Asap
