What is the percentage overhead of a system that sends 11 seven-bit ASCII characters as a block proceeded by 1 start bit, then followed by 0 parity bits and 2 stop bits? The bit time for this system is 0.00032 seconds per bit. Provide your answer with no units and give two places after the decimal point (yes you need a decimal point in this case). Do not provide units and do not use the % symbol, though you should give your answer as a percentage.
