Mul_fact=30e3/Freq_dev# Multification factor
print ' Freq deviation is %f Hz\n Multification factor is %d\n corresponding modified max freq deviation is 30114kHz'%(Freq_dev,Mul_fact)
 Freq deviation is 17.453293 Hz
 Multification factor is 1718
 corresponding modified max freq deviation is 30114kHz
