Q. |
## In polybinary signalling method the present bit of binary sequence is algebraically added with number of previous bits. |

A. | j |

B. | 2j |

C. | j+2 |

D. | j-2 |

Answer» D. j-2 | |

Explanation: in polybinary signalling method the present binary digit of the sequence is formed from the modulo-2 addition of the j-2 preceding digits of the sequence and the present digit. |
