Frequency deviation

1.

Frequency deviation corresponding to a 10101010 sequence is at least 80% of the frequency deviation

corresponding to a 00001111 sequence. Positive frequency deviations represent a logic level ‘1’ and

negative frequency deviations represent a logic level ‘0’ as defined in [
