The Nyquist zero-ISI criterion is concerned primarily with?

  • APulse shaping to avoid interference at symbol sampling instants
  • BIncreasing thermal noise
  • CGenerating AM sidebands
  • DReducing antenna length
Report an error
Correct Answer: A. Pulse shaping to avoid interference at symbol sampling instants
Explanation: Nyquist pulse-shaping conditions allow neighboring pulses to have zero contribution at the desired sampling instants, ideally eliminating ISI.
