Serial transfer of CN

Question

In synchronous serial transfer,  if 3 eight bit sync., characters are included in 30 eight bit information character and the bandwidth of cable is 1200 bits per sec. Then calculate the data rate of receiver.

Answer 1

3 eight bit SYNC Characters -------------> 30 eight bit INFO Characters

(3*8) = 24 SYNC bits ------------> 240 INFO bits 

(24*1200) / 240 <---------- 1200 bits 

=> 120 SYNC bits 

(1200 - 120) bits/sec

Ans. 1080 bits/sec 

Comments

can also be 135 characters/sec.

Yes both are equivalent.
