Question: An asynchronous transmission system employs unsynchronized transmitter and receiver clocks, both of which are controlled by quartz crystals. It is guaranteed that the worst-case frequency difference between the clocks will never exceed 0,01 percent. A designer wishes to transmit long bursts of data asynchronously over a serial data link. Each data burst employs a start bit, a single parity bit, and a stop bit. What is the maximum permitted burst length if the designer caters for a maximum frequency error between transmitter and receiver clocks of 80 percent of the stated worst case? (The designer cannot employ the stated worst case value-why?
