Final answer:
The transmission rate of information bits (TRIB) is approximately 239,759.04 bits per second when using 8-bit ASCII, with 1,492 characters in each frame, and 20 overhead characters per frame. This calculation takes into account the transmission speed, error rate, and turnaround time.
Step-by-step explanation:
The formula for the transmission rate of information bits (TRIB) is given by:
TRIB = [(Number of bits in each frame) / (Time taken to transmit each frame)]
Let's calculate each variable:
Number of bits in each frame = (Number of characters in each frame) × (Number of bits in each character)
Time taken to transmit each frame = (Time to transmit the frame) + (Turnaround time)
The time to transmit the frame can be calculated as:
Time to transmit the frame = (Frame size) / (Transmission speed)
Now, let's plug in the values and calculate:
Number of characters in each frame = 1,492
Number of bits in each character = 8 (for 8-bit ASCII)
Frame size = (Number of characters in each frame) + (Overhead characters per frame)
Transmission speed = 155 Mbps
Error rate = 0.01 (1%)
Turnaround time = 40 milliseconds
Using the given values, we can calculate:
Number of bits in each frame = 1,492 characters × 8 bits/character = 11,936 bits
Frame size = 1,492 + 20 = 1,512 characters
Time to transmit the frame = 1,512 characters / 155 Mbps = 0.0098 seconds
Time taken to transmit each frame = 0.0098 seconds + 0.04 seconds (turnaround time) = 0.0498 seconds
Now, let's calculate the TRIB:
TRIB = 11,936 bits / 0.0498 seconds = 239,759.04 bits/second
Therefore, the transmission rate of information bits (TRIB) is approximately 239,759.04 bits per second.
