In signaling scheme, the bit error rate can be reduced by

A Increasing the bandwidth
B Decreasing the bandwidth
C Increasing data rate
D None of the above
Answer & Explanation
Option: [D]

In signaling scheme, decreasing the data rate can reduce the bit error rate. Increasing bandwidth will led to an increase in error rate because higher amount of data traveling at the same time. Also, if data rate is increased, they are more prone to interference from external signals.
