'''IRIG Code B Calculation''':

'''Bit rate''' = 100 Hz = 100 * (1 / second) = 100 / second = 100 / 1000ms = 1 / 10ms

'''Bit time''' = 1 / (Bit rate) = 1 / (1 / 10ms) = 10ms

There are 100 '''Bits per frame'''.

'''Frame time''' = (Bits per frame) * (Bit time) = 100 * 10ms = 1000ms = 1 second

'''Frame rate''' = 1 / (Frame time) = 1 / 1 second = 1 Hz

The bits are modulated on a carrier. A three-digit suffix specifies the type and frequency of the carrier, and which optional information is included:
