想問一下各位前輩在書上的一題關於DSBSC的 Considera composite wave obtained by adding noncoherent carrier Ac‧cos(2 pi fc t + phi)to a DSBSC wave cos(2pi fc t)m(t). This composite wave is applied to an ideal envelope detector. Evaluate this out put for a)phi=0 b)phi=\=0 and |m(t)|<<Ac/2 拜託大大指點了萬分感謝 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 116.59.102.48
