What is Carson’s rule? Explain it.
Carson’s rule provides a thumb formula to calculate the bandwidth of a single tone wideband FM. According to this rule, the FM bandwidth is given as twice the sum of the frequency deviation and the highest modulating frequency. However, it must be remembered that this rule is just an approximation.
According to the statement, the mathematical representation is
