Pulse modulation (pam)

  1. 1. Pulse Amplitude Modulation (PAM) VPAM must directly proportional with VM
  2. 2. Signal shown of PAM Signal In the noise aspect, this type of signal is EASILY EFFECTED by noise This is type of flat-top sampling signal
  3. 3. Construction of PAM signal Time Domain Frequency Domain
  4. 4. Sampling Methods in PAM Ideal and natural sampling signal can eliminate noise Ideal sampling signal is difficult to generate
  5. 5. Detection of PAM Sample Signal fo for the LPF must within the range of fm < fo < fs - fm fs = 2fm but usually fs > 2fm because to have GUARDBAND fm = fs / 2 = 1 / 2T ms(t) = VPAM
  6. 6. Generation and Detection of PAM Generation of PAM Detection of PAM
  7. 7. Generation and Detection of PAM Generation of PAM Detection of PAM
