Calculate the bit error rate. Input frequency is 64KHz. Channel Duration time is 5 seconds.Erroneous bits are 5000.Select one:a. 0.02469b. 0.015625c. 0.0267d. 0.032

49. A channel has a bit rate of 20 kbps. The stop and wait protocol with frame size 4500 bits is used. The delay for error detection and sending ACK by the receiver is 0.25 seconds because of a fault. Find the maximum efficiency of the channel if the destination is 30000km away and the speed of the propagation of the signal is 2.8X108 m/s. Find the decrease in efficiency due to the fault

The bit-rate of a signal is 6000 bps. If 1500 signal elements are sent per second, calculate the Baud Rate and the number of bits in each signal element.

In a communication system each data packet consists of 10001000 bits. Due to the noise, each bit may be received in error with probability 0.10.1. It is assumed bit errors occur independently. Find the probability that there are more than 120120 errors in a certain data packet.

A message comprises a set of symbols which are to be mapped onto binary code words for transmission. The code word set is {000000, 000111, 010010, 100001, 110011, 111000}. How many bit errors in a code word can be reliably detected? (Type a number only - no units.)

A coded orthogonal BFSK modulated signal is transmitted over a Gaussian channel. The signal is non-coherently detected and hard decision decoded. Find the decoded bit error probability if the coding is a Hamming (7, 4) block code and the received Eb/N0 is equal to 10 dB: 28.72×10−3 4.6×10−3 28.72×103 5.714
